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, wobbly aspic when it cools.
- Whites of 2 eggs
- Bind to cloudy particles as they cook, collecting them so the liquid can be clarified.
- Lemon
- Adds acidity that brightens the flavour of the clear liquid.
- White vinegar
- Adds acidity that helps the egg whites coagulate and clarify the liquid.
The step that matters
Boil for 3 minutes, then let it stand until clear. Egg whites must be added to the liquid before it boils, then it is briefly boiled so the whites coagulate and trap cloudiness. Boiling too long or stirring vigorously can break up the raft and leave the aspic cloudy.
Swap the mace
How well each one fits the dish's main ingredients (lemon, tarragon, vinegar, onion, egg, celery):
- Parsleyfits better
- Dillfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against lemon, tarragon, vinegar, onion, egg, celery. Candidates are from the same food group and used in at least 100 recipes.
