Hahaha yeah my mom thought my brownies weren't potent so once. When I came back from school, she was bumbling in the kitchen muttering about gay sex and how scary the lake looks. Funny stuff.
You know what, I always just used the word "crockpot" as an operating word. I suppose what I do would also be better described as a double-boiler.
However, if they tell you to put it in a jar, don't; jars leak as the metal that composes the cap expands from the heat, even if you test it to be waterproof first.
