Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Good stock
- Provides the flavoured liquid that the set aspic is built from.
- Leaf gelatine
- Sets the liquid into a firm, wobbly jelly as it cools.
- Egg white
- Whisked into the hot stock, it collects impurities so the aspic can be clarified.
The step that matters
Simmer without stirring. Stirring during the simmer breaks up the egg white raft before it can trap cloudy particles, leaving the aspic murky instead of clear.
Swap the tarragon
How well each one fits the dish's main ingredients (pepper, vinegar, egg):
- Tarragonthe original
- Dillfits about as well
- Parsleyfits less well
- Allspicefits less well
Fit is the average pairing score against pepper, vinegar, egg. Candidates are from the same food group and used in at least 100 recipes.
