1 oz to 1lb (4 sticks) this will work well but I o 2oz to 1 lb and what this allows me to do is make better tasting treats. Better tasting? you asking right? The logic behind that is for example, I make cookies that require 1 stick of butter, rather than using 112g of canna butter I can use 60g canna butter and 52g regular butter thus almost completely eliminating the green taste in the cookies.
The way I do it is to first grab the container I am going to use when I'm done to let the butter settle in the fridge, I fill it up with water (to about a 1/2" below the top) and pour that in a 3gal pot, I than toss in my butter and bring it to a boil, once it boils I toss in herbs and let boil for 15 min than bring it down to low and removed my pot for an hour or 2 so it can cool (if you don't do this it'll take forever to get it down to temp). I let it simmer at around 120f for 24-48 hours… than using a cheese cloth strain it into the container we filled with water earlier and put a lid on it than pop it in the fridge for a day.
