I had only used it for stuff like oatmeal. Today I made hamburger helper type goulash out of some leftovers I had in the fridge. Left over chili and stewed tomatoes with some macaroni and seasonings.
I really didn’t expect it to work, but it did-quicker than I thought it would.
Basically, you boil water and add it to the thermos to heat it up. Pour out the water and bring to boiling again-maybe even including your other ingredients.
Add back to thermos with the ingredients, put on the lid, shake it to mix it up, and go about your business. I wrapped my thermos in a bath towel, because it was a cheapo, and I figured the insulation wouldn’t be good enough. They advise to lay it on it’s side to cook better.
Very interesting. I looked up the process. I would imagine it would work well for grits, perhaps potatoes if they were cut small. Squash maybe, again cutting it small.
