Ingredients
For the cheese sauce
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 1/2 cup (120 ml) dark ale or stout
- 1 teaspoon English mustard powder
- 1 teaspoon Worcestershire sauce
- 1/4 teaspoon cayenne pepper
- 8 oz (225 g) sharp aged cheddar, finely grated
- 2 tablespoons whole milk
- 1 large egg yolk
For the toast
- 4 thick slices of rustic sourdough or country bread
- 1 tablespoon softened butter
- Flaky sea salt, to finish
Directions
- Melt the butter in a small saucepan over medium heat, then whisk in the flour and cook for 1 minute until bubbly and lightly golden to form a roux.
- Slowly pour in the ale while whisking constantly and simmer until thickened, about 2 minutes. Stir in the mustard powder, Worcestershire sauce, and cayenne.
- Reduce the heat to low, add the grated cheddar a handful at a time, and stir until completely melted and smooth. Mix in the milk for a looser consistency.
- Remove the pan from the heat and let cool for 1 minute, then beat in the egg yolk until fully incorporated; this gives the sauce a silky, custard-like body.
- Preheat the broiler to high. Butter both sides of each bread slice and toast under the broiler for 1-2 minutes per side until lightly golden.
- Spoon the warm cheese sauce generously over each toasted slice, spreading it to the edges so the bread is fully covered.
- Return the toast to the broiler and cook for 2-3 minutes until the cheese is bubbling, puffed, and spotted with deep brown patches.
- Finish with a light sprinkle of flaky sea salt and serve immediately while hot and molten.
Cook’s Notes
- Use a strong, aged cheddar such as Sharp English or Irish cheddar for the best tangy bite; blending in a little Gruyère adds nutty depth.
- A dark ale like Guinness gives the most traditional flavor, but a brown ale or even a splash of dry cider works well.
- Toast the bread on both sides before topping so it stays crisp under the rich sauce and does not turn soggy.
- Watch the broiled toast closely in the final minute; cheese can go from bubbling to burnt very quickly under high heat.
- Leftover cheese sauce keeps in the fridge for 2 days; rewarm gently with a splash of milk to bring it back to a spreadable consistency.
