Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Their rich, creamy texture forms the body of the filling.
- Minced meat
- Adds savory flavor and substance to the yolk filling.
- Mustard
- Adds sharpness that balances the richness of the yolks.
- Lemon juice
- Adds acidity that brightens the filling in place of vinegar.
The step that matters
Mix the yolks with the meat and seasonings. The yolks must be broken down smooth so the filling holds together and spreads evenly. Lumps or uneven mixing leave pockets of dry or overly rich bites, and the filling can be piped or spooned back into the whites more cleanly when fully blended.
Swap the mustard
The recipe marks mustard as optional. How well each one fits the dish's main ingredients (egg, ham, lemon, vinegar, cheese, parsley):
- Mustardthe original
- Shallotfits about as well
- Asparagusfits less well
- Capsicumfits less well
Fit is the average pairing score against egg, ham, lemon, vinegar, cheese, parsley. Candidates are from the same food group and used in at least 100 recipes.
