Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the main body of the dish, becoming tender after gentle simmering.
- Egg yolks
- Thicken the sauce as they set gently with heat, giving it body and richness.
- Butter
- Adds richness and fat, carrying the flavour of the nutmeg and sugar during cooking.
- Velouté sauce
- Provides a savoury base that gives the finished dish body and a smooth texture.
The step that matters
Incorporating the egg yolk and milk mixture. Egg yolks set at modest temperatures and can scramble if the pan is too hot or they are added without moderating. Keep the heat low and stir steadily so the sauce thickens smoothly instead of curdling.
Swap the cucumber
How well each one fits the dish's main ingredients (vinegar, butter, nutmeg, sugar, sauce, egg, milk):
- Capsicumfits better
- Shallotfits better
- Mustardfits better
- Cucumberthe original
Fit is the average pairing score against vinegar, butter, nutmeg, sugar, sauce, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
