I'm a truck driver, and I have a minifridge, a microwave, an Instant pot, and an electric water kettle on the truck with me. I've been experimenting with various ideas on how to best feed myself. So here's my version of the question. If I cook the soup with some veggies and meat, scoop some out to eat, and seal the lid and keep the instant pot set to "Keep Warm" (145-175 degrees F) will it be safe? It stays sealed except when I'm dishing out a new dish, it stays above 140 degrees, and each time I add new stuff to it, I'll re-cook it, but will whatever I've left in there still be good?
I was just reading through this question: Never ending soup; is it actually safe? and I had a modified version of it to ask, but since that question hasn't been active in over a year, I thought I would make a new question.
