Shred the sharp cheddar and drain the jar of pimentos.
Chop the pimentos into smaller pieces.
Add the softened cream cheese and mayonnaise to a large bowl. Beat using a hand mixer until smooth and combined.
Add the shredded cheddar, chopped pimentos, black pepper, garlic powder, onion powder, and cayenne pepper to the whipped cream cheese mixture. Fold to evenly combine.
Serve immediately, or cover and refrigerate until ready to serve.
* I prefer freshly shredded cheddar for the best flavor and consistency. Sharp cheddar gives this pimento cheese a bolder, cheesier flavor, but mild cheddar will also work if you prefer a softer flavor.**I use Duke’s mayonnaise, which is a classic Southern mayo with a rich and tangy flavor. You can use any mayonnaise you like or already have on hand.
