Not at all surprised it was invented by observant Jews for the sabbath -- cholent (which we always just called "the soup" and IMO was the best thing my maternal grandmother made, although I may have been the only one of the grandkids that liked the grainy dissolved beans).
I've got three: a regular-size round one, an oval one, and a small round one. These days, I have a couple recipes I use my crockpot for (I don't have an Instant Pot): Nihari, stews (just did an osso bucco a couple weeks ago), but mostly they're used to keep things warm at parties. I can't conceive of making pulled pork there when smoked is so much better, and we just don't eat a lot of beans.
What is patriotism, but the love of good things we ate in our childhood?
