Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓

Ingredients
Directions
Prepare the stock
Break the beef into small pieces and wash the meat well.
Place the beef, calves' feet, veal, carrots, onions, parsley, and water in a large stewpan.
Bring the stew to a boil, then reduce heat and simmer until the liquid is reduced by half, skimming off fat as needed.
Remove the pot from heat and let it stand for a few minutes.
Strain the liquid through a colander and a clean cloth.
Let the liquid cool.
Remove all fat and grease.
Clarify and flavor
Whisk the egg whites in a pint of water.
Warm the jelly.
Stir the egg mixture into the warm jelly.
Allow the mixture to boil for 15 minutes.
Strain the mixture through a jelly bag.
Warm the jelly again.
Flavor the jelly with tarragon and lemon juice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Coagulate as they heat, trapping cloudy particles so the jelly becomes clear.
- Calves' feet
- Release gelatin during long simmering, giving the stock its setting power.
- Shin of beef
- Adds deep meaty flavor and body to the stock as it simmers.
- Knuckle of veal
- Contributes gelatin and savory flavor to the stock.
- Lemons
- Add acidity that brightens the flavor of the finished jelly.
The step that matters
Stirring the egg whites into the warm jelly and boiling. Egg whites must be stirred in evenly and allowed to coagulate fully during boiling, which lifts impurities. Boiling too vigorously before they set, or skipping the straining afterward, leaves the aspic cloudy and less clear.
Swap the onion
How well each one fits the dish's main ingredients (beef, veal, carrot, parsley, egg, tarragon, lemon):
- Shallotfits better
- Leekfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against beef, veal, carrot, parsley, egg, tarragon, lemon. Candidates are from the same food group and used in at least 100 recipes.
