Why would you do it for 10 minutes? That's a waste. I know he's using a lot of stuff, but it simply makes no sense to try and stir-fry the pot butter.
Good cannabutter needs long time, low temperature.
At 10 minutes on medium, with that much butter, the entire batch of butter would barely even heat before you remove it. Sorry mafeeker, but you are simply incorrect.
