Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooking cheese
- Melts into a smooth, rich sauce that forms the body of the dish.
- Egg yolks
- Thicken the sauce and add richness as they set gently with the cheese.
- Ale
- Thins the cheese mixture and adds a malty, slightly bitter flavour.
- Butter
- Adds fat that makes the cheese sauce smooth and glossy.
The step that matters
Stirring without boiling. Egg yolks scramble if they get too hot, so the sauce must be stirred gently over low heat until creamy. Boiling curdles the eggs and makes the sauce grainy.
