Cheese Toast

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Preheat your oven to 400°F (200°C).

Make and assemble

  1. In a bowl, mix the butter, mustard, and salt until well combined.

  2. Spread the mixture on the slices of toast.

  3. Top each slice with grated cheese.

Bake and serve

  1. Place the toast in the oven and bake until the cheese is melted and bubbly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Adds richness and moisture, and helps the surface brown in the oven.
Mustard
Adds a sharp tang that balances the richness of the butter and cheese.
Bread
Forms a crisp base that holds the topping.
Cheese
Melts into a creamy, bubbling layer that browns on top.

The step that matters

Baking until melted and bubbly. Cheese melts and then keeps heating, so the proteins tighten and the fat separates, making it greasy, tough, or burnt. Watch it closely and take the toast out once the cheese is melted and bubbling.

Swap the mustard

How well each one fits the dish's main ingredients (butter, bread, cheese):

  1. Tomatofits better
  2. Potatofits about as well
  3. Onionfits about as well
  4. Mustardthe original

Fit is the average pairing score against butter, bread, cheese. Candidates are from the same food group and used in at least 100 recipes.
