Why it works: Lemon and tarragon 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 ↓

Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the stock
Combine 1 quart of water, chopped onion, peppercorns, celery seed, bay leaves, and lemon rind in a large pot. Bring to a boil.
Reduce heat and simmer for 30 minutes. Strain the mixture to remove solids.
Set the aspic
Add vinegar, tarragon vinegar, and lemon juice to the strained liquid.
Dissolve the gelatin in a small amount of warm water and stir into the mixture.
Beat the eggs and mix them in thoroughly.
Pour the mixture into a mold and refrigerate until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Instant powdered gelatin
- Forms the firm, trembling gel that lets the aspic set when chilled.
- Vinegar
- Adds sharp acidity that brightens the flavor and balances the savory liquid.
- Tarragon vinegar
- Contributes a distinct herbal aroma and tangy acidity to the finished aspic.
- Lemon juice
- Adds fresh acidity and citrus aroma that lift the flavor of the liquid.
The step that matters
Dissolve the gelatin fully before stirring it in. Gelatin must be completely dissolved in warm water so it disperses evenly. Undissolved granules can form lumps or weak spots, and the aspic may not set uniformly when chilled.
Swap the onion
How well each one fits the dish's main ingredients (gelatin, lemon, tarragon, vinegar, celery, egg):
- Mustardfits better
- Lettucefits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against gelatin, lemon, tarragon, vinegar, celery, egg. Candidates are from the same food group and used in at least 100 recipes.
