You can also roll the butter into a log, chill it and then slice it into individual pieces. Place the blended butter on a piece of plastic wrap, shaping it into a rectangle. Wrap the butter tightly in the plastic wrap, folding the sides in first and then the top and bottom. Roll into a log and refrigerate until firm. To serve, cut 1/4- to 1/2-inch slices and arrange them in a butter dish.
