Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sardines
- Provide the main savoury, oily flavour and the bulk of the topping.
- Melted butter
- Adds richness and moisture to the sauce, carrying the seasonings over the fish.
- Prepared mustard
- Adds sharp, pungent flavour that cuts through the richness of the fish and butter.
- Lemon juice
- Adds acidity that brightens the flavour and balances the oily sardines.
- Cayenne pepper
- Adds gentle heat that gives the sauce its characteristic kick.
The step that matters
Heat the sardines without cooking them. Sardines are already cooked and become dry and rubbery if overheated. Warming them just until hot keeps them moist and tender, and keeps their oil from turning bitter.
Swap the mustard
How well each one fits the dish's main ingredients (butter, pepper, lemon):
- Capsicumfits better

- Mustardthe original
Fit is the average pairing score against butter, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
