Jim Early took first place out of 300 entries in the Southern Foodways Alliance Pimiento Cheese Invitational by creating this update of his mother's recipe. If you need a smaller amount, you can easily cut the recipe in half.
Process first 3 ingredients, in batches, in a food processor 45 seconds or until well blended. Add pimiento and next 4 ingredients, and pulse 5 to 6 times or to desired consistency. Cover and chill up to 1 day. Serve with crackers or bread slices.
