Pimiento Cheese

Obviously not for every day consumption but great for parties.

1 1/2 cups (packed) finely grated extra-sharp yellow cheddar cheese (about 6 ounces)
1 1/2 cups (packed) finely grated extra-sharp white cheddar cheese (about 6 ounces)
1 cup mayonnaise
1/4 cup diced drained pimiento peppers from jar, roasted red peppers, or piquillo peppers (about 2 1/2 ounces)
1/4 teaspoon cayenne pepper
Celery sticks
Ritz crackers

Mix first 5 ingredients in medium bowl. Mash with fork to blend well. Season with salt and pepper. Cover; chill until cold, at least 2 hours and up to 3 days. Serve pimiento cheese with celery sticks and Ritz crackers, or, if desired, spread between 2 slices of white bread and cut diagonally to make 4 sandwich triangles.
