Ingredients
Directions
Prepare
Knead the butter, mustard, and cayenne together on a plate.
Prepare one slice of buttered toast, trim the edges, and cover with half the cheese sliced thinly.
Spread on half the butter, then add the remaining cheese slices and cover with the rest of the butter.
Cook and serve
Cook in a Dutch oven over the fire until the cheese is melted.
Serve as hot as possible.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cheshire or cheddar cheese
- Melts into a creamy, binding layer that gives the toast its body and flavor.
- Butter
- Adds richness and moisture, helping the cheese melt smoothly and not turn dry.
- Dry mustard
- Adds a sharp, pungent note that balances the richness of the cheese and butter.
The step that matters
Cook until the cheese is melted. Heat must be gentle enough to melt the cheese fully without scorching the toast or making the fat separate and turn greasy.
Swap the mustard
