I took a class on making rso years ago….the easiest method we learned was using a big huge stainless mixing bowl, with the infused booze mixture in the bottom of it. The bowl was so big, an entire mason jar of liquid just covered the bottom. The heat was applied using a camping stove burner (outdoors)….the guy just turned the burner to medium low, and just held, and swirled the bowl with the mixture above the flame….like a foot above it….swirling around so the mixture is boiling at the edges….he kept doing this until 80% of the liquid was evaporated….then he added back 1/4 cup of water….evaporated until that was almost gone….added more water…. And kept that up until the final product was a smooth goo. It took a while (not bad)….but was safe, and the end product was clean and top shelf.The video I watched the other day of them making RSO they used a machine like yours I think They boiled off the alcohol using it as a crockpot with lid open
With other methods it’s hard to get all of the infusion booze out…. And you end up with a weird grainy/liquid mixture….
