I'm just wondering how to warm my mhrb spice soup back up there's no Naphtha in it I left it sit for like a week. I'm trying to find other ways of increase in a yield by letting it soak for a little bit but I'm just now curious at how I am going to warm that cold soup back up. It is STB there's 50mg mhrb 50mg lye 400ml of water.

Put some sand/a lid to suspend the glass jar in some warm/barely boiling water. Don't let the bottom of the jar touch the bottom of the pot, or it can get too hot and crack/break.

Safe travels!

I recommend either putting your jar on a coffee cup warmer (also sold as candle warmers) or my personal favorite, a sous vide heater. I love that method best, as you can dial in the exact temp you want to raise your base liquid to (I usually get it between 110F and 140F for a few hours at least)

I've had excellent results that way.
