not my recipe
don't use butters, I do use Canola oil.
Heat up stove, at Medium Low heat, about 200 degrees. Heat canola oil, I use 1/2 cup of oil + 2 tblspoons extra for what is normally absorbed. Heat the oil, I use 1/4 oz. of duff (leftovers after vaporization) and 1/4 oz. good buds. Grind all materials together and take a pinch and add to heated oil. If it sizzles, then the oil is too hot, turn it down and try again in a few minutes. When the greens no longer sizzle when added to the frypan, add all of your ground up material and immerse that in the oil. Continually stir for approx. 40 minutes. Allow this to cool, then strain out the leaf material. For this I use a gold coffee filter (under $10 at Meijer's). Press the material to remove the oil. The oil can be used in alot of different recipes, including baked mixes, to make salad dressings and added to a pot of spaghetti...etc...I use boxed mixes to make my muffins, just check before buying to make sure that they take oil. I get about 5 dozen mini-muffins from 1/2 cup of oil. That's enough to medicate 60 normal medical users....or less if the persons are large in stature. My dosing is based on a 150 lb. person
