Guessin' there are a ton of great methods to make cannabutter/oil. For me, the methods of cooking for hours STINKS up your home. I take my toaster oven outside and decarboxilate 2 oz. of cannabis on parchment paper in a tray in the oven. I don't even break up the buds and add any kief that has accumulated in the bottom of my grinder. Cook it at 225 for 1/2 hour. Then, I take 4 cups of coconut oil that I melt in the microwave and mix in 3-4 tblsp. sunflower lecithin. The lecithin is a healthy addition that will boost the oompf of your cannabis. Dump the cannabis into the mixture and bake at 250 for 1 hour, stirring it a time or two during the bake. Be careful taking it out of the oven because hot oil can burn you. I'v put cheese cloth in a collander that drains into a bowl. Pour the oil into the cheesecloth and let drain until only warm to the touch. Then, squeeze all of the goodness out of the cheesecloth. Then I pour the oil into the same glass, pint jars that I bought it in. Screw on the lid and keep in a cool, dark location. It's good for months and doesn't need refrigeration. This has only taken me 1 1/2 hours total and the oil is killer to cook with.
