Why it works: Butter and cheese are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 7,962 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Oyster Rarebit
Ingredients
Directions
Prepare the oysters
Clean and remove the hard muscle from the oysters.
Parboil the oysters in their own liquor until their edges curl, then transfer to a hot bowl.
Make the rarebit
In a dish, combine the butter, cheese, salt, mustard, and cayenne.
While the butter melts, beat the eggs slightly and mix in the oyster liquor.
Gradually add the egg mixture to the melted cheese, then stir in the oysters.
Serve
Serve immediately over hot toast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main flavour and tender texture once parboiled until their edges curl.
- Cheese
- Melts into the sauce, giving it body, richness and savoury flavour.
- Eggs
- Thicken the cheese mixture into a smooth, creamy sauce as they gently set with heat.
- Butter
- Melts with the cheese to add fat and a smooth, rich texture.
The step that matters
Adding the egg mixture to the melted cheese. Eggs can scramble if they meet hot cheese too quickly. Adding the egg mixture gradually and stirring keeps the proteins evenly warmed, so the sauce thickens smoothly instead of curdling.
Swap the mustard
