Place the butter in a medium bowl and cream with a wooden spoon or rubber spatula. Add the remaining ingredients and mix well. Place on a large sheet of plastic wrap and form into a cylinder, about 1 1/2-inches in diameter. Roll up in the plastic wrap, pushing in as you go, to form a tight log. Refrigerate or freeze until needed.
To use, unwrap, cut 1/2-inch slices, and serve on top of the New York Strip.
