Soften butter and beat in cheese and seasonings until smooth. Mix in flaked crabmeat. Split English Muffins and cut each half into quarters. Spread 1 tablespoon (or a little more) mixture on each quarter. Freeze on a cookie sheet in one layer (not touching). When frozen, store in plastic bag. To serve, remove from freezer, place on cookie sheet and broil until bubbly and crispy (about 3 - 5 minutes). May substitute chopped corned beef, if desired. ENJOY!!
