Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Form the creamy, rich base of the filling once mashed with the other ingredients.
- Melted butter
- Adds fat and richness, giving the yolk filling a smooth, silky texture.
- Mustard
- Adds sharp, pungent flavor that balances the richness of the yolks.
- Vinegar
- Adds acidity that brightens the filling and cuts through the richness.
The step that matters
Mix the yolk mixture thoroughly. Yolks must be fully blended with the butter, mustard and vinegar so the filling is smooth and evenly seasoned. Lumps of yolk or unmixed liquid leave the filling grainy and unevenly flavored.
Swap the mustard
How well each one fits the dish's main ingredients (egg, pepper, butter, vinegar, parsley):
- Shallotfits better
- Capsicumfits better
- Chivefits about as well
- Mustardthe original
Fit is the average pairing score against egg, pepper, butter, vinegar, parsley. Candidates are from the same food group and used in at least 100 recipes.
