Why it works: Veal and onion are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 6,841 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Mock Turtle Soup
Ingredients
Directions
Prepare the head
Remove the brains from the calf's head and clean it thoroughly, especially the nostrils and ears.
Soak the head in cold water for 1 hour.
Place the head in a stew-pan with 6 quarts of cold water and bring to a boil, skimming off any scum.
Let it simmer for 1.5 hours.
Remove the head from the pot.
Cool the head.
Cut the head into 1 to 1.5 inch pieces.
Cut the tongue into smaller pieces.
Store the meat in a deep pan.
Cover the meat with some of the broth to prevent drying.
Make the broth
Add the bones and trimmings of the head and the knuckle of veal to the broth in the stew-pan.
Bring the broth to a gentle boil.
Cover the pot.
Simmer for 4 to 5 hours.
Strain the soup into an earthenware pan.
Let the strained soup cool.
Stir the soup occasionally while cooling.
The next morning, remove the layer of fat from the top.
Place the clear jelly into a stew-pan.

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Provides gelatinous skin, bones and meat that give the soup its body and rich texture.
- Knuckle of veal
- Adds bone and connective tissue that release gelatin, thickening the broth as it simmers.
The step that matters
Skimming the scum at the first boil. Impurities rising from the head during the first boil cloud the broth and add off-flavours if not removed. Skimming keeps the finished soup clear and clean-tasting.
