Why it works: Mustard and vinegar are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
Prepare the toast
Cut slices of roll into oval or octagon shapes and toast or fry them in oil or butter until golden.
Make the sardine paste
Remove the bones from the sardines, setting half aside and pounding the other half into a smooth paste with the egg yolks and butter.
Mix in the mustard, pepper, and vinegar until well combined.
Assemble and serve
Spread the sardine paste over the prepared toast slices.
Top with the reserved sardine strips and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Bind the paste and add richness and a smooth, creamy texture.
- Butter
- Adds fat and richness, helping the paste spread smoothly.
- Sardines
- Provide the main savory flavour and the fish base of the paste.
- Vinegar
- Adds acidity that brightens the rich sardine and egg flavour.
- Mustard
- Adds sharp, pungent flavour that balances the richness of the fish and yolks.
The step that matters
Pounding the sardine paste smooth. If the sardines and yolks are not worked until smooth, the paste stays lumpy and hard to spread. Fully breaking down the fish and yolks with the butter gives an even, creamy texture.
Swap the mustard
How well each one fits the dish's main ingredients (egg, butter, pepper, vinegar):
- Capsicumfits better
- Mustardthe original
- Shallotfits about as well
- Cucumberfits about as well
Fit is the average pairing score against egg, butter, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
