Why it works: Shallot and vinegar are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 2,374 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
Prepare the stock
Combine the white stock, shallots, bay leaf, fine herbs, and gelatine in a stewpan.
Heat the mixture, stirring until the gelatine dissolves.

Mix the egg whites with the cold water and vinegar.
Combine the egg white mixture with the jelly.
Return the stewpan to the heat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the liquid into a firm, sliceable jelly as it cools.
- Egg whites
- Collect impurities during heating, clarifying the stock into a clear jelly.
- White stock
- Provides the main liquid and savoury flavour of the aspic.
The step that matters
Bringing the mixture to a boil. Boiling the egg white mixture lets the whites coagulate and trap cloudy particles, which then strain out. Stirring or boiling too vigorously before straining can break up the raft, leaving the aspic cloudy.
Swap the shallot
How well each one fits the dish's main ingredients (veal, egg, vinegar):
- Cucumberfits about as well

- Shallotthe original
- Asparagusfits about as well
Fit is the average pairing score against veal, egg, vinegar. Candidates are from the same food group and used in at least 100 recipes.
