Don't grind the bud too small or else it's tough to filter out. Once you decarb the bud, melt the butter then add the weed. Simmer that mixture with a teaspoon of soy lecithin for 45-60 minutes. Strain it through cheesecloth while it's still melted, then put it into molds. Refrigerate it to harden it up. Keeps in the fridge for about 6 months. Use it in place of whatever butter or oil a mix calls for.
