Stovetop cholent does have a tendency to stick”
Mine does not. I have a simmer ring (perforated metal disc heat diffuser) on top of my burners and under the blech, so the cholent pot is, in effect, in a double burner, as far as the heat is concerned. Nothing ever burns, especially if the burner is on low to begin with. I always put the cholent up to be nearly cooked by Shabbos. Then it goes on the blech as I described. You can also try spraying th bottom of the pot with PAM before putting the ingredients in. Maybe that will help. And yes, there is no comparison between stove top and crockpot cholent. I don’t know why.
