How to Make It
Combine all ingredients in a food processor. Pulse until ingredients are blended but some chunks remain, about 4 times. Spoon mixture onto plastic wrap, and shape into a 1-inch-thick log. Wrap completely in plastic wrap; chill 30 minutes.
Remove and discard plastic wrap. Slice butter crosswise into 2-tablespoon portions, and serve on hot grilled steak, fish, or poultry.
