What is "Welsh rarebit"?

Welsh rarebit is a traditional British dish that is made with a cheese sauce that is poured over toasted bread. The cheese sauce used in Welsh rarebit is typically made with cheddar cheese, flour, butter, milk, and beer or ale, which gives the sauce a rich and savory flavor. The sauce is cooked on the stove until it is thick and bubbly, and is then poured over slices of toasted bread. The bread and cheese sauce are then broiled until the cheese is melted and bubbly. Welsh rarebit is often served as a lunch or dinner dish, and can be enjoyed on its own or with a side salad or vegetables.
