Like our Cheddar Scones, these muffins can be served over the course of the day, starting with breakfast. These are just the thing for a fall picnic or informal buffet. If you are looking for a simple, chic snack, split these in two, top each half with paper-thin slices of prosciutto or smoked ham, and serve a little chutney or chow-chow on the side. A reminder for whenever you plan to serve them: Make them with real Cheddar, the only acceptable kind.
