Hi. I use mine at least once a week... steam vegetables (about 3-4 minutes for most)
and that's usually starting to time it from when the gauge starts to go up.
Potatoes, whole, take about 10 minutes and they taste just like baked potatoes.
I tried putting stale bagels in there, just to try it, and they came out pretty good.
KFC uses a PC to cook their chicken I hear, but I'm not sure of the details.
Rice works, but I've never done it in there.
