Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw eggs
- Thicken the sauce as they set gently when hot mixture is whipped in.
- Hard-boiled egg yolks
- Form a smooth, rich base that gives the sauce body.
- Melted butter
- Adds fat and silky richness to the sauce.
- Vinegar
- Adds acidity that sharpens the flavour of the sauce.
- Tomatoes
- Soften and brown over the coals, giving a sweet, mellow flavour.
The step that matters
Gradually add the hot mixture to the beaten eggs, whipping until smooth.. Adding hot liquid to raw egg slowly while whisking tempers it, so the eggs warm evenly and thicken smoothly instead of scrambling into lumps.
Swap the tomato
