Veggie stuff, probably about 4-6 days. Some things I know I have kept longer. Meat dishes, sometimes maybe 4 days. I'm sure I've probably gone longer. I figure if it gets heated long and hot, I'll be ok.
Rice - I had heard ages ago that rice should never be reheated but tell that to the Burmese. Most do not have ice boxes and usually make a huge pot of rice in the morning. My wife and her family cook rice in the morning and leave in the pot all day (unheated) and scoop from the pot throughout the day and reheat it as necessary. And in the morning, if any is left over they will eat it. They don't have an ice box.
I used to always treat rice the same as other staples, then there was this revelation and I stopped keeping rice but then I went to Burma and now I do keep rice and will eat it the next day too. Never experienced any problems. Now between the experience of dw's rice habits and the fact that rice pudding is kept and reheated, I can't find fault with it. But how dangerous is reheating rice? Is it still consider a no-no? How dangerous is not refridgerating rice?
