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 ↓

Drain the salmon and separate into flakes.
Make the custard

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Forms the body and flavour of the mould.
- Egg yolks
- Thicken the mixture and add richness when cooked gently.
- Gelatine
- Sets the salmon mixture so it holds its shape when chilled.
- Flour
- Thickens the custard base, giving it body and a smooth texture.
- Whipping cream
- Adds air and a light, creamy texture to the cucumber sauce.
- Butter
- Adds richness and a smooth mouthfeel to the custard.
The step that matters
Cooking the custard in a double boiler. Egg yolks thicken as they heat but can scramble if overheated. Gentle, indirect heat from a double boiler lets the mixture thicken smoothly without curdling, which keeps the base silky before the gelatine and salmon are added.
Swap the mustard
How well each one fits the dish's main ingredients (salmon, sugar, flour, egg, butter, cream, vinegar):

Fit is the average pairing score against salmon, sugar, flour, egg, butter, cream, vinegar. Candidates are from the same food group and used in at least 100 recipes.
