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

What each ingredient does

Oysters
Provide the main savoury seafood flavour and tender texture when cooked until the edges curl.
Eggs
Bind the mixture and thicken it into a rich, custard-like texture when gently heated.
Melted cheese
Adds richness, savoury flavour and a smooth, creamy body to the sauce.
Melted butter
Adds fat for richness and a smooth texture to the mixture.

The step that matters

Stir in the melted cheese until well combined. Cheese can turn grainy or stringy if it is overheated or added too fast. Melting it gently into the warm egg mixture keeps the sauce smooth and cohesive.

Swap the mustard

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