Welsh rarebit, a classic dish of cheese sauce on toast, with beer, mustard, and Worcestershire sauce.

All this cooked into a sauce, and ladled over toast, then broiled in the oven for a bit:

¼ cup butter

¼ cup all-purpose flour

½ teaspoon salt

¼ teaspoon pepper

¼ teaspoon dry mustard

¼ teaspoon Worcestershire sauce, or more to taste

2 drops Tabasco, or more to taste

1 cup whole milk

½ cup beer

½ pound sharp Cheddar cheese, shredded
