I must admit I still put frozen meat on the counter at night to be cooked the next day......
had a relative that would stuff turkey, put in oven very low at nite and it cooked overnite...now talk about a Petrie dish....but having eaten at the table...no one ever got "sick"...... Maybe our peasant genes were strong enough to fend off any attack of bad bacteria......
thought I read somewhere that the fear of "bad" mayo in salads was strongly exaggerated.....
....and I can definitely see the encouragement of using this in some other cultures.....
and crockpots are like a pot on stove on simmer...heat is consistent and regulated.....but I'm not a scientist so my thinking may be all wrong.......I do know this is not on my wish list!
