Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grated cheese
- Melts into the sauce to give it its rich, savoury flavour and body.
- Egg yolk
- Enriches and thickens the sauce, helping it hold together when poured over toast.
- Milk
- Forms the liquid base that the cheese melts into, keeping the sauce smooth.
The step that matters
Add the egg yolk gently. Egg yolk thickens through gentle heat. Adding it to a very hot mixture or stirring it too hard can scramble it, leaving lumps instead of a smooth, creamy sauce.
