In a large mixing bowl, combine the cream cheese, sour cream, Worcestershire sauce, horseradish, buttermilk, lemon juice, and black pepper.

Using an electric mixer, beat until smooth and well combined.

Fold in the chipped beef and chopped pickles, stirring until evenly incorporated.

You can serve it immediately, but for the best flavor, cover and refrigerate overnight.

Serve with your favorite chips or crackers.
