From My Carolina Kitchen by Sam Hoffer
I made my own, eyeballing the ingredients as I did as a child. Start with freshly grated cheddar cheese (I used both a yellow and a white cheddar), then add some chopped roasted red peppers or pimentos, stir well, then add just enough mayonnaise to bind the cheese so the mixture will spread easily. If you like your pimento cheese spicy, add some fresh seeded and chopped jalapenos and a dash or two of Tabasco. If not using right away, it will last, covered, for several days in most people’s refrigerator.
