Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gruyere cheese
- Melts into a smooth, creamy sauce and gives the rarebit its rich, nutty flavor.
- Eggs
- Set when heated, thickening the cheese mixture into a spoonable sauce.
- Butter
- Adds fat that keeps the melted cheese smooth and glossy rather than grainy.
The step that matters
Stir in the eggs and cook until thick. Eggs thicken through gentle heat. If the pan is too hot or the mixture is cooked too fast, the proteins tighten and curdle, leaving the sauce grainy. Keep the heat low and stir constantly.
