stovetop in a pot, 2-3 hours, little over half pound butter, 18g vaped buds, 1g mids, 0.4g of keef, 1 cup water...everything between 2-4 on stove dial to simmer. Strained through regular paper coffee filter, refrigerated, got about half full tub(used empty Smart Balance) of cannabutter but some dark liquid gathered at the bottom, emptied dark liquid. Made Betty Crocker Hershey& peanut butter brownies with the cannabutter, 2 small dark liquid holes in brownies but after dumping it out carefully & baked at 100 degrrees lower than directions & they came out great...3 brownies got me high for remainder of the night!
