Step 1: In a large mixing bowl, combine the softened cream cheese (if using) and mayonnaise. Mix until smooth and creamy.
Step 2: Add the garlic powder, onion powder, Worcestershire sauce, hot sauce, and black pepper to the mayonnaise mixture. Stir well to combine, ensuring all seasonings are evenly distributed.
Step 3: Gently fold in the thoroughly drained diced pimentos into the mixture. Mix until evenly distributed throughout the creamy base.
Step 4: Add the freshly grated sharp cheddar cheese to the bowl. Using a sturdy spoon or spatula, fold the cheese into the mixture until all the cheese is coated. Be careful not to overmix, which can make the cheese tough.
Step 5: Taste the pimento cheese and adjust seasonings if necessary. Add a pinch of salt if desired, but often the cheddar provides enough salinity. For an extra kick, add more hot sauce.
Step 6: Cover the bowl tightly with plastic wrap and refrigerate for at least 1-2 hours, or preferably longer (overnight is ideal). This allows the flavors to meld and deepen, resulting in a more delicious pimento cheese.
Step 7: Before serving, let the pimento cheese sit at room temperature for about 15-20 minutes to make it easier to spread. Serve with crackers, fresh vegetables, or as a sandwich spread.
