In a large bowl, combine shredded cheddar cheese, red onion, and pimento or roasted peppers.
In a smaller bowl, combine garlic, and mayonnaise. Add to the cheddar cheese mixture, blending thoroughly. Add white pepper and sir well to combine. Cover and refrigerate at least 2 hours or overnight for flavors to blend before serving.
Bring to room temperature before serving.
I like to serve in a small crock. Great spread on crackers, stuffed into celery sticks, dip for crudites, and/or as a filling for a sandwich.
* I substituted Peppadew Sweet Piquante Peppers. Pepperadews have a unique, delicious taste, a mixture of peppery and sweet, but with a distinctive flavor. Try them - you'll like them! I always buy all I can find in my grocery store just to keep them handy for when I want to use them in my cooking.
