English muffins are small, round, flat (or thin) type of yeast-leavened bread which is commonly sliced horizontally, toasted, and buttered. Contrary to some sources, which attribute the muffins to a version invented in the United States by an English immigrant, Samuel Bath Thomas, the recipe was based on a popular bread product that was sold door-to-door in Victorian-era Britain and published in cookery books such as Mrs Beeton's. Toasted English muffins, which are often served as a breakfast food, are served with sweet toppings (e.g., jam or honey) or savoury toppings (e.g., cooked egg, sausage rounds or bacon and cheese). Mr. Thomas probably brought the recipe with him or recreated it from a cookery book.
