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 ↓
Moulded Salmon
Ingredients
Directions
Make the dressing
Make a salad dressing with the first six ingredients.
Soften the gelatine in cold water.
Dissolve it in the hot dressing while stirring constantly, then strain the mixture.
Set and serve
Add the salmon to the dressing and pour it into a moistened mold.
Chill the mold until set, then unmold onto a bed of lettuce.
Garnish with parsley and hard-cooked eggs or olives, and serve with additional salad dressing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the dressing and salmon into a firm, sliceable mold when chilled.
- Eggs
- Add richness and help bind the dressing into a smooth, thick emulsion.
- Mustard
- Emulsifies the dressing and adds sharp, savory flavor.
- Vinegar
- Adds acidity that brightens the rich dressing and balances the fish.
- Salmon
- Forms the body of the mold, giving the dish its flesh texture and main flavor.
- Sugar
- Adds gentle sweetness that rounds out the acidity of the vinegar and mustard.
The step that matters
Dissolve the gelatine fully in the hot dressing. Gelatine only sets properly when fully dissolved. Undissolved granules or clumps leave soft spots and a weak, uneven set, so stir constantly until the mixture is smooth before straining and adding the salmon.
Swap the mustard
