In large bowl, combine cream cheese, sour cream, mayonnaise or Miracle Whip, lemon juice, Worcestershire sauce, mustard and garlic salt until smooth. Add enough milk to make creamy. Stir in half of grated cheese. Fold crabmeat into cheese mixture. Pour into 1 quart casserole. Top with remaining cheese. Bake 325 degrees until mixture is bubbly and browned, about 30 minutes. Serve with Sociables or other crackers.
