1 cup mayonnaise
1 (7-ounce) jar diced pimiento, drained and rinsed
1 teaspoon Worcestershire sauce
1/2 teaspoon garlic powder
1/4 to 1/2 teaspoon cayenne pepper
1 (8-ounce) block extra-sharp Cheddar cheese, shredded (about 2 cups)
1 (8-ounce) block smoked Gouda cheese, shredded (about 2 cups)
Don't skip the step of rinsing your diced pimiento. Otherwise it will be too salty. For the creamiest pimiento cheese, buy the cheese in blocks and shred by hand.
