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

What each ingredient does

Cheese
Melts into a smooth sauce that forms the body of the rarebit.
Eggs
Thicken the cheese sauce as they set gently with the heat.
Oysters
Provide the main seafood flavor and a tender, briny texture.
Butter
Adds richness and helps the cheese melt smoothly without sticking.
Mustard
Adds a sharp tang that balances the richness of the cheese.

The step that matters

Combining the egg mixture with the melted cheese. Eggs can curdle or scramble if they meet high heat too quickly. Adding the egg mixture gradually and keeping the heat moderate lets it thicken into a smooth sauce.

Swap the mustard

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

  1. Capsicumfits better
  2. Asparagusfits about as well
  3. Potatofits about as well
  4. Mustardthe original

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