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 or Savoury Jelly
Ingredients
Directions
Make the stock
Cut the meat and break the bones into small pieces.
Place them in a stewpan with a plate at the bottom to prevent burning.
Add 6 quarts of cold water and bring to a boil, skimming off any foam.
Add cloves, bay leaf, onion, shallot, garlic, pepper, and salt.
Simmer for 7-8 hours until reduced to a third of its original quantity.
Strain off the jelly and fat, and let it cool completely.
Clarify and finish
Remove all fat from the surface and wipe with a warm, damp cloth.
Re-melt the jelly in a clean enamelled saucepan and squeeze in lemon juice.
Beat in the slightly beaten egg whites and crushed shells.
Heat to boiling, stirring continuously, and boil for 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Meat
- Provides the gelatin-rich body and savory flavor that form the jelly as it simmers.
- Cow heels
- Supply collagen that converts to gelatin, giving the stock its firm setting power.
- Egg whites
- Bind to cloudy particles as they heat, so they can be strained out for a clear jelly.
- Lemon juice
- Adds acidity that brightens the flavor and helps the clarified jelly taste fresh.
The step that matters
Heat to boiling while stirring continuously. Stirring keeps the egg whites and shells from settling and scorching on the base, and the rising egg white mass traps impurities so they can be filtered out, clearing the jelly.
Swap the onion
How well each one fits the dish's main ingredients (meat, clove, shallot, garlic, pepper, lemon, egg):
- Chivefits better
- Spinachfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against meat, clove, shallot, garlic, pepper, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
