In a mixer fitted with the paddle, combine the cheese, chopped pimentos, mayonnaise, black pepper and garlic powder; blend at low speed. Season the pimento cheese with Cayenne Pepper to taste. Cover and refrigerate for 2 hours.
Make Ahead – the pimento cheese can be prepared and refrigerated for up to 3 days before making the rest of the recipe. Of course, if you want to take a shortcut, just buy store bought!
