This was my father's recipe. With his coastal southern accent, it always sounded like he was saying "Welsh Rabbit." Only when I was older did I discover there was nothing rabbit about this rare bit! I think he always used milk as the liquid in his recipe, and that was usually a can of evaporated milk. I have used the traditional beer in mine, but either works well. My father always used extra sharp Cheddar. In these pictures, I have used white Cheddar and Gouda. You serve it over toast points. A favorite of my family when we were children, and also of my own children.
