Ingredients
300 gsharp cheddar cheese
40 gbutter
240 mlbeer or ale
5 gEnglish mustard powder
10 mlWorcestershire sauce
8 piecesbread slices
2 gcayenne pepper
3 gsalt and black pepper
Instructions
1TOAST THE BREAD: Preheat your broiler or toaster oven to medium-high heat. Toast the bread slices until they are golden brown and crispy on both sides, approximately 3-4 minutes. The bread should be firm enough to support the cheese sauce without becoming soggy. Set the toasted bread aside on a heat-safe serving tray.
2PREPARE THE CHEESE SAUCE: In a heavy-bottomed saucepan over medium heat, melt the butter slowly, stirring gently to ensure it doesn't brown. Once melted, add the mustard powder and whisk thoroughly for about 30 seconds to eliminate any lumps and activate the mustard's flavor. This preliminary mixing ensures the mustard distributes evenly throughout the sauce.
3ADD THE BEER: Gradually pour the beer into the butter and mustard mixture while whisking constantly to prevent lumps from forming. The mixture will initially look loose and separated, but continue whisking until it becomes relatively smooth. Bring the mixture to a gentle simmer over medium heat, allowing it to reduce slightly for about 2 minutes, which concentrates the beer's flavors and creates a silky base.
4INCORPORATE THE CHEESE: Reduce the heat to low and add the grated cheddar cheese in three batches, stirring thoroughly after each addition and waiting until the cheese is completely melted before adding more. The cheese should melt smoothly into the sauce without any graininess; if it becomes too thick, add a splash more beer or a tablespoon of milk. The sauce should have a consistency similar to thick cream, coating the back of a spoon.
5SEASON THE SAUCE: Stir in the Worcestershire sauce and adjust the seasonings with cayenne pepper, salt, and black pepper to taste. The sauce should be peppery with a slight heat from the cayenne and a savory depth from the Worcestershire. Taste and adjust accordingly; remember that the seasonings will intensify slightly as the sauce cools, so season conservatively and you can always add more.
6ASSEMBLE AND BROIL: Pour the hot cheese sauce generously over each slice of toasted bread, ensuring even coverage. Place the assembled toasts on a broiler-safe tray and slide them under the preheated broiler for 2-3 minutes until the top is bubbling and lightly browned. Watch carefully to prevent burning—the topping should be golden with light brown spots. Serve immediately while the sauce is still bubbly and the cheese has a molten texture.
