Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓
Aspic Jelly
Ingredients
Directions
Make the stock
Combine chopped calves' feet, ham or bacon, game, poultry, cutlet trimmings, uncooked meat, onions, carrots, clove, garlic, spices, herbs, pepper, and salt in a stewpan.
Add 1½ cups of cold water or broth.
Cover the pot.
Heat on a brisk fire, shaking occasionally.
When the meat begins to color, add 1½ cups of hot water or broth.
Simmer for 3-4 hours.
Strain the mixture through a fine strainer.
Remove any fat once cooled.
Clarify and finish
Beat the egg whites in a saucepan.
Melt the jelly slightly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calves' feet
- Release gelatin, which sets the cooled liquid into a firm jelly.
- Egg whites
- Bind to impurities as they heat, so they can be removed to leave a clear aspic.
- White tarragon vinegar
- Adds acidity that brightens the flavor of the clear jelly.
- Onions
- Add savory depth and aroma to the stock as it simmers.
The step that matters
Stirring in the egg whites until boiling. Egg white proteins coagulate as they heat and trap cloudy particles. Stirring them in while the liquid is brought to a boil, then letting it settle, lets the impurities rise and be strained off, giving a clear jelly. Stirring too late or too hard can leave it cloudy.
Swap the clove
How well each one fits the dish's main ingredients (ham, beef, onion, carrot, garlic, pepper, egg):
- Parsleyfits better
- Celeryfits better
- Thymefits better
- Clovethe original
Fit is the average pairing score against ham, beef, onion, carrot, garlic, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
