Why it works: Tarragon and vinegar are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,547 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Salmon Moulded in Jelly
Ingredients
Directions
Make the jelly
Soak the gelatine in enough cold water to cover it.
Heat the gelatine in a saucepan with the clear stock until dissolved, then let it cool.
Whisk the egg white with cold water and tarragon vinegar, then stir into the jelly.
Allow the mixture to boil for 10 minutes without stirring once scum forms.
Set aside to settle for 10 minutes, then strain through a jelly bag until clear.
Set and serve
Boil the salmon in a small amount of water until cooked, then cool and cut into 1‑inch squares.
Pour a little jelly into a mold and arrange pieces of salmon, alternating skin and pink flesh on the outside.
Let the jelly set, then add another layer of salmon and cover with jelly, repeating until the mold is full.
Once completely cold, turn the jelly out of the mold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the clear stock into a firm jelly that holds the salmon in shape.
- Egg white
- Clarifies the stock by trapping particles, which are then strained out for a clear jelly.
- Salmon
- Forms the cooked fish filling that is set inside the jelly.
- Clear stock
- Provides the liquid base that the gelatine sets into a savoury jelly.
- Tarragon vinegar
- Adds a light acidity that brightens the flavour of the jelly.
The step that matters
Clarifying the jelly by boiling with egg white. The egg white coagulates as it heats, collecting cloudiness and scum. Stirring after scum forms breaks up the raft and leaves the jelly cloudy, so it must be left undisturbed, then strained through a jelly bag until clear.
Swap the tarragon
How well each one fits the dish's main ingredients (egg, vinegar, salmon):
- Dillfits better
- Capersfits about as well
- Tarragonthe original
- Parsleyfits less well
Fit is the average pairing score against egg, vinegar, salmon. Candidates are from the same food group and used in at least 100 recipes.
