In a separate bowl, combine diced pimentos (with their juice) and mayonnaise. Add to the cheese, toss to combine, and season with salt and pepper.
Serve as a dip with fresh vegetables, spread on bread as a sandwich, or on top of crackers.
Notes
Since you're only using three ingredients in this recipe, it's really important to choose the highest quality cheese and mayonnaise that you can find. Grab a really great block of sharp cheddar -- that's the flavor that you will taste the most!
Do not use pre-shredded cheese from a package. It's best if you grate the cheese by hand or in a food processor just before using.
Allow the pimento cheese tosit on the counter for about 30 minutes before serving. This will make it softer and easier to spread.
If you're preparingpimento cheese sandwiches, you'll need approximately ⅓ - ½ cup of the cheese spread per sandwich. This recipe will make about 6-7 sandwiches. For 10 -15 sandwiches, for instance, you'll need to double the recipe. For 50 sandwiches, you would need about 25 cups of pimento cheese spread (or about 7 batches of this recipe).
