Smokin' is the goto guy for brining on the bbq circuit.
We find that his brines help us take the breast to around 167 º,so we have that extra cushion.
Using the oven,for hotter cooking,you may find that folks are checking deep in the thigh for about 165º.
Yes,our families followed the gov't safety guidelines-if they ever saw an internal therm.
Pork would be cooked forever,or at least to 180º-185º at 350º,and let the carryover carry it up to 200º.
Now chefs may pull out at 137 º and let the carryover go to 145º.
Many families liked beef pot roast,as it could cook forever,or maybe 250º.
Yes,gravy was a natural necessity in many of our homes.
As I said,there are cooks that can pull it all off,and I treasure them.
Many worked very hard for long periods of time.
Our family of deep coal miners got a turkey from the company at holidays.
We always fought to get the nice 28 pounder to stuff and cook.
Chefs will get two 14 pounders,and put the dressing in a pan to finish the last 45 mins.
As to warnings,we don't hear them about uncooked eggs in mayo,raw oysters on the half shell, tobacco,or ground beef,or unwashed lettuces,or granny's potato salad and deviled eggs in the warm picnic sun,or salmonella from poultry,or sugar in the diet,or saturated fats,or excess salt,or letting the large Thanksgiving meal set out all day for visitors,leaving the uncooked poltry out on the kitchen counter,for a few hrs,.....whoops,maybe we are now hearing these?
Difficult for the gov't to say "if you cook everything to our no margin of a problem,you probably won't like to eat it".
Think how many food producers/campaign contributors might sue.
Hard for a food producer to start out scaring off the consumer and crippling their industry.
I'd say that most producers recommend cooking unstuffed poultry,and using special precautions/handling-if you chose to cook it stuffed.
Yes,I've cooked them stuffed.
Maybe now,I find the ease of producing a consistent,quality product,with the concern for risk minimized ,aids my decision making.
Just a thought.
