clarify your butter or use ghee. This is the trick to making a good butter. Clarified (ghee) butter has a high burn temp and doesn't require water to cook. I clarify my butter, add butter and weed into bowl and cook in over @220 degrees for 1 hr... very little smell, works great.
edibles- I used 20 grams to make 1 cup of cannabutter, then brownies... awesome buzz and neighbors loved it. Although, mine turned out on the "couch lock" side of the buzz.
