Cluster Haven's Pepper Mill Cheese Ball

From The Splendid Table

Ingredients

1 stick butter

1 8-ounce package cream cheese

1 1/2 cups grated Cheddar cheese

2 tablespoons grated onion

2 tablespoons coarsely ground pepper (to get really coarse pepper, I put peppercorns in a dish towel and bang it with a mallet on my floor)

Combine the butter and cream cheese. Add in the Cheddar and onion. Mix it really well. Form it into a ball and roll it in the pepper. Refrigerate. Serve at room temperature on a Ritz.
