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 ↓
Savory Jelly
Ingredients
Directions
Prepare the liquor
Take the cold liquor from braised poultry, meat, or veal stock, ensuring it is free from fat.
Warm the liquor and strain it through a fine sieve into a clean saucepan.
Season with coarse sea salt, lemon pickle, cayenne pepper, and tarragon or vinegar to taste.
Add enough dissolved isinglass to achieve the desired stiffness.
Clarify and cook
Whisk in plenty of egg whites, a small amount of yolks and shells, and a little liquid for color.
Heat over a fire until boiling, then let it simmer for 15 minutes.
Strain through a jelly bag several times until perfectly clear.

Lemon and egg barely smell alike, yet cooks put them together in 44,316 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whites of eggs
- Coagulate as they heat, trapping impurities so the liquid clears.
- Dissolved isinglass
- Sets the liquid into a firm jelly as it cools.
- Liquor from braised poultry or meat, or veal stock
- Provides the savory body and flavor that the jelly is built on.
- Tarragon or plain vinegar
- Adds acidity that brightens the savory flavor.
The step that matters
Clarifying with egg whites. The whites must be whisked in before heating and the liquid kept from boiling hard, so the proteins coagulate slowly and gather impurities. Stirring them in too late or boiling vigorously leaves the jelly cloudy.
Swap the tarragon
How well each one fits the dish's main ingredients (meat, lemon, pepper, egg):

- Tarragonthe original
Fit is the average pairing score against meat, lemon, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
