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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calves' feet
- Release gelatin that lets the cooled liquid set into a firm jelly.
- Egg whites
- Coagulate as they heat, trapping particles so the aspic becomes clear.
- White tarragon vinegar
- Adds acidity that brightens the flavor of the finished aspic.
- Onions
- Add savory depth and aroma to the simmering stock.
- Carrots
- Contribute sweetness and aroma to the simmering stock.
The step that matters
Stir the egg whites into the boiling stock. Egg whites must be whisked into the stock before boiling and left undisturbed as they heat. As they set they gather cloudy particles and float them to the top, which clarifies the jelly. Stirring them in too late or breaking the crust can leave the aspic 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.
