BKS is the ultimate for sure...her recipes rock! You really don't want to use water when making your oil or butter...
remember that 1 oz bud = 4oz trim approx.
1. decarb: grind material like you would for a joint. Spread out in oven safe pyrex (I use a 13 x 9 for my 150 gram batch). cover tightly with foil. put in cold oven and set temp to 220f and timer for 20 mins. Let cool to room temp.
2. If using butter, clarify it or melt your coconut oil (olive works great too, especially for vinagrettes

then add to you decarbed material. Re-cover it with the foil and place in preheated oven to 215f and set timer for 1 hour. Let cool completely then put in freezer for at least 2 hours (I let it go overnight).
You can stop here if you want, just heat enough to remelt the butter and strain (nylons work great) or you can cook it again at same time and temp, only for 2 hours the second cook. then strain.
You can keep the strained material and simmer it in a half gallon of whole milk (if using 150 grams starting material, less milk for less material). You can use the milk for, well, any damn thing lol
mac and cheese, hot cocoa, oatmeal...
After you have strained your butter, pour into either half cup or 1 cup freezer safe containers and store in freezer. If going to use within a couple weeks, the fridge is fine. But it WILL mold if left longer than a couple weeks in fridge.
