What each ingredient does
- American cheese
- Melts into a smooth, creamy sauce that coats the toast.
- Ale
- Thins the melted cheese into a pourable sauce and adds a malty flavor.
- Bread
- Provides a sturdy, crisp base that holds the hot cheese sauce.
The step that matters
Melting the cheese over medium heat. Cheese proteins toughen and the fat can separate if it gets too hot, leaving a grainy or oily sauce. Gentle heat and steady stirring keep the sauce smooth.
