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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the clear broth into a firm, wobbly jelly as it cools.
- Chicken broth
- Forms the savoury liquid base that becomes the aspic.
- Egg white (in the method)
- Clarifies the broth by collecting cloudy particles so it stays clear.
- Tarragon vinegar
- Adds a sharp, acidic note that brightens the savoury flavour.
The step that matters
Clarify the broth. Egg white is heated with the broth so its proteins coagulate and trap cloudy particles. Straining through flannel then removes them, giving a clear, glossy aspic rather than a murky one.
Swap the tarragon
The recipe marks tarragon as optional. How well each one fits the dish's main ingredients (chicken, vinegar, sherry):
- Garlicfits about as well
- Tarragonthe original
- Thymefits about as well
- Peppermintfits less well
Fit is the average pairing score against chicken, vinegar, sherry. Candidates are from the same food group and used in at least 100 recipes.
