Why it works: Mustard and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,356 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Molded Salmon
Ingredients
Directions
Prepare the salmon
Remove skin and bones from the salmon and break it into small pieces.
Make the custard
In a bowl, mix mustard, salt, sugar, egg yolks, thin cream, and vinegar.
Cook the mixture over simmering water until it thickens like custard.
Remove the mixture from heat.
Add soaked Knox gelatin to the mixture.
Strain the mixture over the salmon.
Mix thoroughly and pour into a mold that has been dipped in cold water.
Set and serve
Set the mold in a cold place until firm.
To serve, turn the mold onto a bed of lettuce and accompany with cucumber sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the cream and vinegar mixture into a custard as they cook and set.
- Knox gelatin
- Sets the mixture so it holds its shape when turned out of the mold.
- Salmon
- Forms the main body of the molded dish.
- Thin cream
- Adds richness and softens the sharpness of the vinegar in the custard.
- Vinegar
- Adds acidity that sharpens the flavour of the custard and salmon.
The step that matters
Cook the mixture over simmering water until it thickens like custard. Egg yolks thicken when heated gently; too much heat scrambles them into grainy curds, so the custard must be cooked slowly over simmering water and stirred.
Swap the lettuce
How well each one fits the dish's main ingredients (salmon, mustard, sugar, egg, cream, vinegar, gelatin):
- Horseradishfits better
- Cucumberfits about as well
- Lettucethe original
- Chivefits about as well
Fit is the average pairing score against salmon, mustard, sugar, egg, cream, vinegar, gelatin. Candidates are from the same food group and used in at least 100 recipes.
