Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Bind the oil and water into a smooth, thick emulsion.
- Cream
- Adds richness and a softer, silkier texture.
- White wine vinegar
- Adds sharpness that balances the richness of the sauce.
- Mustard
- Helps hold the emulsion together and adds a sharp flavor.
The step that matters
Stirring the mixture on the stove. Egg yolks can scramble and curdle if they overheat. Stirring constantly spreads the heat evenly, so the sauce thickens smoothly instead of turning grainy.
Swap the mustard
How well each one fits the dish's main ingredients (cream, egg, pepper, white wine, vinegar):
- Capsicumfits better
- Spinachfits about as well
- Shallotfits about as well
- Mustardthe original
Fit is the average pairing score against cream, egg, pepper, white wine, vinegar. Candidates are from the same food group and used in at least 100 recipes.
