Pimento cheese is basically a cheese salad of sorts, with cheddar, store-bought mayo, and jarred pimentos. You could get upscale and take it to the park with crackers and a bottle of rosé, but I like to serve it right up on some white bread and get a little sandwich action going. That's how we do it down South.
In a large bowl, combine both Cheddars, pimentos, mayonnaise, and chipotles. Mix well. Add the Worcestershire and juice from half a lemon.
Chop the green tops of the scallions, add to the cheese mixture, and mix again. Add more cheese if necessary for a balance of cheese and mayonnaise, so the mixture is nice and thick, not runny. Season with salt, pepper, a few dashes of hot sauce, and mix again. Serve the traditional way, on sliced white bread.
