Homemade Blackberry Butter - I need to make this for my family because we all like blackberries and I have some in our freezer from last harvest. 1 pound salted butter, softened, 1/8 cup of honey, 1/2 cup blackberries. Whip together butter and honey until fluffy. Add in berries and mix in short bursts until desired look is achieved. Spoon into a wide-mouth glass jar and store in the refrig.
