Berry Butter

1/4 cup berries such as raspberry or blackberry
1 stick butter, softened

Cream the butter in a mixer using the paddle attachment. Add the berries and mix briefly just until berries break up.  Turn mixture onto a sheet of parchment paper, spooning a line across the center.  Roll up the parchment paper to form a cylindrical shape. Place in refrigerator until firm. Serve with bagels, toast, scones, French toast, etc.
