a piece of toast with cheese sauce on it that is heated until the sauce melts

I have already given you a recipe for cheese on toast, but Welsh rarebit is quite different.

The cheese is mixed with beer and toasted on bread to form a delicious Welsh Rarebit.

The cheese was grated and melted with milk or ale to make Welsh rabbit.

The success of a rarebit depends to a great extent upon the quality of the cheese.

Top the rarebits with some chopped fresh herbs.
