Why it works: Mustard and capers match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 624 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Cheese Croutons

Oven, in the book's wordsA quick oven

Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Make the croutons

  1. Fry the bread rounds in a pan until golden brown.

  2. Sprinkle a thin layer of dry mustard over each round.

  3. Add a layer of grated cheese on top, then season with salt and pepper.

  4. Place the rounds in a 400°F (200°C) oven until the cheese is melted.

Serve

  1. Top each crouton with a spoonful of hot rice and garnish with capers.

  2. Serve immediately while hot.

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

What each ingredient does

Bread rounds
Provide the crisp base that holds the toppings.
Grated cheese
Melts over the bread to add richness and savoury flavour.
Dry mustard
Adds a sharp, pungent flavour that cuts through the cheese.

The step that matters

Place the rounds in a 400°F (200°C) oven until the cheese is melted.. Cheese can burn or turn greasy if overheated, while too little heat leaves it unmelted. Watching the cheese closely lets it melt smoothly and brown lightly.

Swap the capers

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

  1. Celeryfits about as well
  2. Capersthe original
  3. Turmericfits about as well
  4. Thymefits about as well

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