Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Welch Rarebit
Ingredients
Directions
Make the rarebit
In a hot stew pan, melt the butter.
Add the cheese pieces and stir immediately until melted and smooth like thick cream.
Mix in Worcestershire sauce, Tabasco, and milk (or beer) as you stir.
Serve
Place a spoonful of the cheese mixture on a toasted cracker and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- American cheese
- Melts into a smooth, creamy sauce that gives the rarebit its body and richness.
- Milk or stale beer
- Adds liquid that loosens the melted cheese so it spreads smoothly rather than turning stiff.
- Worcestershire sauce
- Adds savory, tangy depth that balances the richness of the cheese.
- Butter
- Fat that melts first in the pan and helps the cheese melt evenly without scorching.
The step that matters
Melt the cheese gently and stir constantly. Cheese proteins tighten and turn grainy or oily when overheated. Stirring steadily while the cheese melts keeps the heat even, so the sauce stays smooth and creamy.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
