Why it works: Tarragon and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,137 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken broth
- Provides the savoury liquid base that the jelly is made from.
- Tomatoes
- Add the main flavour, colour and acidity to the stock.
- Leaf gelatine
- Sets the flavoured liquid into a firm, sliceable jelly as it cools.
- Egg whites and shells
- Bind fine particles during clearing so the finished jelly is clear rather than cloudy.
- Tarragon vinegar
- Adds sharpness and a light herbal aroma that balances the tomato.
- Carmine or cochineal
- Adds a red colour to the jelly.
The step that matters
Clear the liquid. Clearing depends on the egg whites and shells slowly trapping fine solids as the liquid heats, so the liquid should be disturbed as little as possible. Stirring or boiling too hard breaks up the raft and leaves the jelly cloudy.
Swap the tomato
How well each one fits the dish's main ingredients (chicken, tarragon, vinegar, lemon, egg, pepper):
- Capsicumfits better
- Shallotfits better
- Mustardfits better
- Tomatothe original
Fit is the average pairing score against chicken, tarragon, vinegar, lemon, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
