    I’m not Italian, I’m not religious, but now that I’ve found a decent fish monger, the Feast of the Seven Fish is the kind of meal I can get behind in support of winter or summer soltisce, depending on your hemisphere.

    Or even for Christmas Eve.

    We did our own version on the barbie: snapper, ocean trout, farmed Tasmanian salmon, big prawns, little prawns, steamed oysters and Morton bay bugs from just up the road a bit, along with some sweet potato crisps and rustic bread (would have gone for Tassie mussels but everyone was sold out, so it was two kinds of shrimp).

    It was a feast, and we were grateful. Everything was cooked to a tender but safe thermometer-verified temperature. The bowl on the right is remnants.

    With five daughters, I’ve put in my share of time at the fundraising-BBQ- cookout, or in Aussie-speak, sausage sizzle.

    Last night was the Christmas concert for Sorenne’s pre-school, which was somewhat surreal the first time – outdoors, everyone in shorts and flip-flops or dressed up fancy-like. For a sub-tropical climate in summer, they go a little nuts about the Christmas thing, with surfin’ Santa’s and shrimp on the barbie by the beach.

    I proudly wore my Kansas State hockey shirt (there is no K-State hockey) and waved around my Comark PDT 300 tip-sensitive digital thermometer – which wasn’t necessary because the staff had precooked the sausages. But as the hundreds of parents and kids poured in (dozens?) me and John Hodgman-lookalike, Clayton, resorted to cooking raw sausage, and the thermometer became a necessary aide.

    No children were harmed in this sausage sizzle.

    I expect companies like ConAgra and government agencies like the department of agriculture to blame consumers when their 50 cent pot pies make hundreds of people barf – just follow the instructions.

    I don’t expect Consumer Reports to blame the consumer when microwave cooking makes people sick. But I have low expectations, especially of so-called consumer groups.

    Consumer Reports latest tests of microwaves found fewer models that aced our evenness test.

    When food isn’t cooked evenly to an internal temperature that kills harmful bacteria that might be present, illness can result, according to the USDA. So using a microwave that delivers even heating is important.

    You’ll need to cook food longer if your microwave’s wattage is lower than the cooking instructions requires. Our Ratings indicate wattage, and you’ll find it on the serial number plate on the back of the microwave, inside the microwave door, or in the owner’s manual.

    The USDA also recommends using a food thermometer to test food in several spots, but the survey found most people don’t, and nearly a third said nothing would change their mind. Using a food thermometer is a good idea, but at the very least, make sure there are no cold spots in your food.

    How? With your tongue? Frozen foods that are going to be cooked in the microwave should contain pre-cooked ingredients.

     In Oct. 2004, I gave a keynote talk at the Food Standards Australia New Zealand food safety conference in the Gold Coast, Australia.

    Before the talk, I did a live bit for one of the morning talk shows – like Good Morning America, but it was Good Morning Australia. Washing shopping carts was of particular interest.

    The interview was done remotely, with me in the kitchen of a somewhat swanky hotel and casino where the meeting was being held. Before we got started, I chatted with the chef about some random food safety stuff. I asked if he served sprouts and he replied he’d worked in southeast Asia, new the risks with raw, and always gave them a quick saute or blanch.

    I also noticed he had a tip-sensitive digital thermometer in the front pocket of his chef’s coat, and I asked if he used it, and he said all the time.

    I asked if I could borrow the thermometer to use as a prop during the interview, and the media person accompanying me said something like, you can’t talk about thermometers, we can’t even get people to refrigerate their food; the fridge is for the beer.

    Seven years later, and the consumer food safety types in Australia have started a push to use thermometers for food safety.

    The Food Safety Information Council recommends meat thermometers be used to decrease the risk of food poisoning, but only 23% of Australian households own a meat thermometer and only a third of those with a one have used it in the last month, according to Council commissioned Newspoll research released today.

    Food Safety Information Council Chair, Dr Michael Eyles said today, “A meat thermometer is a vital piece of kitchen equipment for both food safety and food quality reasons making it surprising that less than a quarter of households have one, and even more surprising that only about a third of those with one say they have used it in the past month.”

    Following the lead of Elizabeth Weise of USA Today who last month wrote of the virtues of thermometers as gifts, Eyles said, “A meat thermometer makes a great Christmas present. … It is not only a small price to pay for the safety of your family and friends but is a minor cost to ensure food is consistently cooked to perfection.”

    The national Newspoll study of more than 1200 respondents, 18 years and over found:

    • Nearly 1 in 4 (23%) households claim to have a meat thermometer at home. This varies across the country, ranging from 27% in Victoria, to 17% in Queensland.

    • Higher income households are significantly more likely to have a meat thermometer. 28% of households with an income of $80,000+ claim to have a meat thermometer, compared to just 17% of households with an income of less than $30,000.

    • Among those who have a meat thermometer, only 1 in 3 (35%) claim to have used it in the last month, with half of these (18%) claiming to have used it in the last week.

    Self-reported surveys like this one still suck – meaning people know the socially acceptable or desirable answer and lie. So the number of people actually using thermometers is overinflated.

    But look at Amy. From learning how to temp a chicken breast in 2005, she’s now using our Comark PDT 300 on bread and cookies to ensure optimum quality (those cookies reached 190-200 F and were excellent). With moving around, different ovens, the humidity, and always trying different recipes, there is significant variability in actual oven temps, moisture levels and heating efficiency. So stick it in.

    An instant-read thermometer is the best gift for the cook who has everything. Here’s what some folks told Elizabeth Weiss of USA Today.

    William Keene, senior epidemiologist at Oregon's Public Health Service, gives instant-read thermometers as wedding presents. "They save people's lives."

    The thermometer also makes Keene's food taste a lot better. That's because after spending a long day talking to people who've gotten sick from eating undercooked food, he found he had a tendency to overcook everything. Food "would get all dried out." But when he used the thermometer he actually stopped when it was done, rather than overdone. Though don't forget to wash the tip with soapy water after you use it, "to avoid cross-contamination.”

    Kathy Bernard of the U.S. Department of Agriculture's Meat and Poultry Hotline gives them out as bridal shower presents. At the holidays they're especially useful when people pull out recipes they don't often make, like eggnog. "Since it contains raw eggs, if you're going to make it from scratch you start cooking the egg base, stirring it over low heat until the mixture reaches 160," to kill any possible salmonella.

    Jack Bishop of America's Test Kitchen, a popular cooking show on PBS, said, "It's something you can be pretty sure most people don't own, or if they do own one, they don't own a very good one.”

    And they're not just for meat, says Bishop. The old-fashioned method of knocking on the bottom of the loaf pan to see if the bread's done only works if you've spent enough years baking bread that you know what you're listening for. With a thermometer there's no guessing. Plain bread is done at between 200 and 210, a sweet loaf between 190 and 200.

    And for cheesecake, a thermometer is the key to avoiding cracks across the top. "The magic temperature is 150," Bishop says

    Old-fashioned meat thermometers rely on metal actually expanding and turning the temperature dial. Digital instant-read thermometers use electronics and are faster and generally more accurate. The instant-read digitals use slightly different technology than a regular digital thermometer, so be sure to look for ones that say they are instant-read.

    Our favorite is the Comark PDT 300 (right, exactly as shown, about $30).

    I started using my thermometer on homemade bread a couple of years ago; big improvement.

    In her somewhat annual Thanksgiving message to barfblog.com, Michéle Samarya-Timm of the Somerset County Department of Health, NJ, gets stuffed.

    At Thanksgiving, if conversation isn’t about the bird, it’s about the stuffing: in the bird, or outside the bird? I teach food safety to a variety of folks, so my stance on this stays consistent…outside and 165 F.

    Attendees at my food safety class last week brought up a refreshingly different question….does it matter what the stuffing is made of?

    I know the barfblog guys are particular about stuffing; Doug wrote about it last Thanksgiving. His refrigerator potpourri technique sounds tasty…a gourmet mélange of basic ingredients. Call it barfblog’s Best Thanksgiving Stuffing, if you will. But this recipe has competition.

    Cookbooks and websites are chock-full of the best-ever stuffing recipes with subtle twists on traditional ingredients. Using bread? Options are endless: Cornbread, multi-grain whole-wheat, sourdough, rye, bagels, and the ever-popular squishy white Wonder Bread.

    Not a bread person? How about a rice stuffing? You can choose from white, wild, saffron, risotto, or last night’s leftover steamed. It’s easy to see how basic substitutions have expanded the variations for grandma’s recipe.

    The advent of processed foods managed to usher in some more kitschy offerings, that surprisingly have cult followings: Corn Flakes stuffing (featured this morning on NPR), Ritz Cracker stuffing, or even White Castle hamburger stuffing.

    I began to wonder about alternate approaches to this traditional side dish. I’ve heard of stuffing made with items such as sausage, lobster, clams, chestnuts, pine nuts, zucchini, or bacon.

    These can all be personalized marks of a creative cook. In addition, I recall many times in my own kitchen when I needed to get inventive for lack of an essential ingredient. So I might be able to understand why there is a recipe for popcorn stuffing. What surprised me were the more unique renditions of this holiday classic that could make a Thanksgiving one to remember:

    Didn’t have time for breakfast this morning? No problem – you can make stuffing from oatmeal, grits, grape nuts or captain crunch.

    Don’t like the taste of turkey? Pair it with stuffing made college-style with pizza…or Italian style with prosciutto, salami and pepperoni …or man-style with steak and bacon.

    For a multi-cultural twist, try tortilla chip stuffing, lasagna stuffing, or a mofongo mix – a Puerto Rican specialty of fried green plantains mashed up with bacon, sofrito and olive oil.

    You could consider the epicurean dish turducken (a chicken stuffed into a duck, which itself is stuffed into a turkey) as the ultimate in stuffing options…or is it?

    I pondered…is there anything edible that can’t be cooked as stuffing?

    I tried searching for the strangest options, and uncovered stuffing recipes containing alligator, applesauce, chocolate (now that may be onto something), peanut butter, Twinkies and donuts.

    Devil Dogs, cookies, pop tarts, matzos, malted milk balls -- you can pretty much put anything in; if it’s edible it can be made into stuffing.

    The key is not the ingredients so much as the food safety. You can make stuffing from homemade cornbread, marshmallow peeps, bologna or rutabaga, so long as you cook it thoroughly and check it with a probe thermometer. 165 F kills a whole host of common pathogens. Kill the pathogens, not your guests.

    Stuffing isn’t evil; cooking it incorrectly is.

    Thankful for all those who keep our families, our food supply, and our country safe.

    Roasting a frozen bird can produce a better turkey.

    And many food safety types agree.

    Elizabeth Weise of USA Today writes the technique involves a hot oven, an icy bird and six hours to hang out with your relatives.

    While the technique turns out not to be new, it's gaining traction because of a Web publication outlining how to do it by Pete Snyder of the Hospitality Institute of Technology and Management, which does safety training for food companies.

    "The breast is still moist and the dark meat is still tender," Snyder says from his office in St. Paul. It's also excellent for food safety "because you didn't drip that nasty turkey juice on everything in the refrigerator for four days."

    Donald Schaffner, a food microbiologist at Rutgers University in New Brunswick, N.J., says from a safety perspective Snyder's right. "A frozen turkey is going to spread less contamination around your kitchen than a thawed turkey."

    Snyder tested the technique because "I had been one of those people that had woken up at 7:30 in the morning and the turkey was still frozen." But being a food-safety professional, he decided to throw in a few temperature-measuring thermocouplers.

    He placed them at various points on multiple frozen turkeys as they roasted. What was happening in the oven, he found, was "the first half of the cooking period thaws the turkey and then the second half roasts it," he says.

    His technique is simple:
    Take one frozen turkey, 12 to 13 pounds.
    Place a low wire rack on a cookie sheet with low sides.
    Remove the plastic cover from the turkey.
    Put the turkey on the rack.
    Put it in a 325-degree oven.
    Wait 4½ to five hours.
    Eat.

    Snyder recommends using a cookie sheet or another baking sheet with a low rim, not a high-sided roasting pan. "You want the hot oven air to evenly circulate all around the turkey," he says.

    He also recommends putting the turkey on a rack on the pan so that the hot air can circulate underneath, as well.

    The U.S. Department of Agriculture's food-safety experts agree with Snyder. Kathy Bernard of USDA's Meat and Poultry Hotline says "you can cook a turkey from a frozen state, the only thing you need to know is that it takes one and a half times longer to cook" than a thawed bird.

    The technique is well known to the folks on the Butterball Turkey Talk-line. They get "lots" of calls on the topic Thanksgiving morning, says Carol Miller. She has been answering frantic questions for 27 years out of the Naperville, Ill., office.

    The ideal final temperatures for the turkey is 160 degrees at the breast and 185 for the legs. But Snyder doesn't think a thermometer is necessary because you can tell when the leg has reached 185 because "it will wiggle back and forth really easily" because the connective tissues will have begun to dissolve at that temperature, he says.

    USDA isn't so keen on the "wigging the leg" method of testing for doneness. "You need to use your food thermometer, you need to make sure the turkey should register 165 in the innermost part of thigh and the thickest part of the breast," Bernard says.

    Butterball's Miller says this is the time to canvass the neighborhood. "You really need a meat thermometer. If you don't have one, give a guest a call and see if they can bring one. Or go to a convenience store. Or knock on a neighbor's door."

    The one area where Snyder and other turkey experts differ is on the matter of the neck and giblets, which in most commercially prepared turkeys will be placed in the neck and body cavity.

    Snyder says that after about 2½ to three hours the turkey will have thawed enough that you can "carefully" pull them out of the warming bird to start to make stock. "You can leave them in, but then you don't have them for the gravy," he says.

    Butterball's Miller disagrees. The bag they come is "designed to go through that heating process, so that's not a problem." Trying to remove a slippery bag tucked deep in a turkey straight out of a hot oven — especially when everyone's stressed about getting things done on time — just isn't necessary. "They're just as happy staying right where they are. That's our recommendation and we've been doing this for 30 years."

    The one thing you can't do with a frozen turkey is deep fry it, because the frozen liquid can cause the oil to boil over, Snyder says. "That would be very, very dangerous."

     Tips for a food safe Thanksgiving dinner are popping up, so Chapman and I, always eager to jump on a bandwagon, came up with our own.

    1. Never wash the Thanksgiving turkey. Research from the U.K. and elsewhere shows that washing turkey or chicken is an ideal way to spread dangerous bacteria throughout the kitchen or food preparation area. Washing under running water can spray surface contamination up to three feet away.

    2. Never place a whole turkey over your head. While it may be a popular attempt at comedy in movies and television shows like “Mr. Bean” or “Friends,” do not inspect the internal cavity of the turkey by placing it over your head. This is potentially the most contaminated part of the turkey.

    3. Make sure to use a tip-sensitive digital thermometer to ensure the turkey has reached 165 F. Color is an inadequate indicator of safety so always use a thermometer to test the turkey before serving.

    4. Cool leftover turkey quickly. Refrigerate leftover turkey within two hours of taking it out of the oven. Some spore-forming bacteria will grow and form toxins if kept at room temperature for too long. Turkey should be cooled to 41 F quickly and this is best accomplished by placing sliced leftover turkey in reseal-able bags of one quart or smaller size. Bags should be laid flat in the refrigerator to allow cool air to circulate.

    5. Do not pass babies with leaky diapers around the holiday table. This can lead to all kinds of food contamination, and does not end well for anyone at the table.

    A table of holiday-meal related outbreaks is available at http://bites.ksu.edu/turkey-related-outbreaks.

     I’ve got turkeys wandering around the yard but I can’t buy one at the grocer or butcher.

    Paul the butcher in Annerley, Brisbane, Australia, took pity on me and gave me – gave me for free – a frozen turkey breast he had in his freezer.

    “If it sucks, throw it out.”

    I threw it out.

    Paul says he does a lot of turkeys for Christmas, but Thanksgiving just isn’t an Australian thing.

    And it’s sorta weird, with spring strawberries and asparagus abundant rather than the traditional North American harvest foods.

    Was even weirder prepping food all morning while Amy played with Sorenne and listened to the K-State football game on Internet radio.

    But, we continued our tradition and had some 15 Aussies over for a Canadian Thanksgiving feast.

    And instead of North American football, there was the 2011 Rugby World Cup quarterfinals: yeah Wales (suck it Ireland); France will lose next weekend to Wales; yeah Australia (suck it South Africa), and in a few hours it should be yeah New Zealand (suck it Argentina).

     As a Canadian citizen with permanent U.S. residency living in Australia, I get confused.

    Even with a language professor by my side, I can barely understand a damn word anyone says – especially the Canadians.

    Fellow Queenslander Pat Dignam also appears confused when he writes in the Irish Times that food irradiation “is routine in some countries, including the U.S., so eating rare hamburgers there is safe.”

    No. A small fraction of American ground beef is irradiated, and almost none of that is available at retail or food service.

    Mr. Dignam is correct when he says, “During the butchering process, the surface of cuts of meat may become contaminated with bacteria, notably E. coli, from the intestines of the animal (regardless of the standards applied by the farmer and butcher). Cooking an intact piece of meat on the surface is sufficient to kill any such bacteria. However, when a piece of meat is minced, contamination on the surface can be spread to any part of the product. … Irish mince is not irradiated, so the process of cooking through is crucial. E. coli infection can be fatal, so anyone who wishes to eat rare or raw minced beef in Ireland should take note of these facts.”

    Well said, except for the U.S. bit. And things get confusing when intact cuts like steaks are needle-tenderized.

    The facts are ground beef in the U.S. needs to be cooked to 160F (71C) as verified by a tip-sensitive digital thermometer.

    Stick it in.
