Ingredients

The following ingredients have 4 Servings
  • 2 tablespoons butter
  • 2 tablespoons flour
  • 1 tablespoon mustard powder, or to taste
  • 1/2 teaspoon cayenne, or to taste
  • 3/4 cup strong dark beer, like Guinness
  • 2 tablespoons Worcestershire sauce, or to taste
  • 1 pound Cheddar, Double Gloucester or other English cheese (or other good semi-hard cheese, like Comté or Gruyère, or a mixture), grated
  • 4 to 8 pieces lightly toasted bread

Instruction

  • Put butter in a saucepan over medium heat and, as it melts, stir in flour. Continue to cook, stirring occasionally, until golden brown and very fragrant, 3 to 5 minutes. Stir in mustard and cayenne, then whisk in beer and Worcestershire sauce.
  • When mixture is uniform, turn heat to low and stir in cheese, again stirring until smooth. Remove from heat and pour into a broad container to set (you can refrigerate for up to a day at this point).
  • Spread mixture thickly on toast and put under broiler until bubbly and edges of toast are crisp. Serve immediately.
