Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Neat's foot
- Provides gelatin, which sets the liquid into a firm jelly as it cools.
- Eggs
- Their whites clarify the liquid, collecting impurities so the aspic stays clear when strained.
- Beetroots
- Add colour and an earthy flavour to the aspic.
- Tarragon vinegar
- Adds acidity and aroma, brightening the flavour of the jelly.
The step that matters
Strain the mixture through a jelly bag. Straining must be gentle and unhurried, because pushing or squeezing the bag lets cloudy particles through. Clarified stock is then clear and sparkling rather than murky.
Swap the onion
How well each one fits the dish's main ingredients (beetroot, parsley, egg, pepper, sugar, tarragon, vinegar):
- Shallotfits better
- Lettucefits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against beetroot, parsley, egg, pepper, sugar, tarragon, vinegar. Candidates are from the same food group and used in at least 100 recipes.
