Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sardines
- Oily fish that supplies the main savoury flavour and rich, tender texture.
- Mustard
- Adds sharp, pungent flavour that cuts through the richness of the fish.
- Vinegar
- Adds acidity that sharpens the flavour and balances the oily fish.
- Butter
- Adds fat that carries flavour and browns the sardines as they fry.
- Toast
- Provides a crisp, absorbent base that holds the sardine.
The step that matters
Fry or grill the sardines. The sardines need enough heat to brown the surface and set the flesh without drying out. Heat that is too low leaves them soggy, while heat that is too high can scorch the mustard coating before the fish is cooked through.
Swap the mustard
How well each one fits the dish's main ingredients (vinegar, pepper, butter):
- Capsicumfits better
- Mustardthe original
- Cabbagefits less well
- Onionfits less well
Fit is the average pairing score against vinegar, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
