Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cheese
- Melts into the sauce and provides the rich, savoury body of the rarebit.
- Milk
- Loosens the melted cheese into a smooth, pourable sauce.
- Butter
- Adds fat for a silky texture and a richer mouthfeel in the sauce.
- Vinegar
- Adds a little acidity that sharpens the cheese flavour and helps keep the sauce smooth.
- Bread
- Serves as the base that holds the sauce on top.
The step that matters
Melt the cheese over low heat. High heat makes the proteins in cheese tighten and squeeze out fat, so the sauce turns grainy or oily. Gentle heat keeps it smooth and cohesive.
