Why it works: Veal and beef are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 3,784 recipes. Both carry 2,6-nonadienal, which smells cucumber, green. The science ↓
Mock Turtle-soup
Ingredients
Directions
Prepare the head
Scald the calf's head.
Split the head.
Remove the brains, nostrils, and bones.
Blanch the head in several waters to remove slime and blood.
Place the head in a stewpan. Cover with cold water. Bring to a boil. Skim off any scum. Boil gently for 45 minutes.
Remove the head. Cut it into small pieces. Peel the tongue. Cut it into 1-inch cubes.
Make the stock
In a stock pot, combine the broken bones and trimmings with the knuckle of veal. Simmer for at least 4 hours.
Strain the stock. Reserve 1 quart for gravy. Remove the fat from the top.
Finish the soup
Add the stock to a large stewpan. Skim again.
Add the fresh herbs and hard-boiled eggs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Provides gelatin and body, giving the soup a rich, thick texture as it simmers.
- Beef bones
- Release gelatin and flavor into the stock during long simmering, deepening its body.
- Veal knuckle
- Adds gelatin and savory depth, helping the stock become full-bodied and lightly thickened.
- Hard-boiled eggs
- Add richness and a mild, creamy texture to the finished soup.
The step that matters
Skim the scum at the start of the boil. Scum and blood proteins rise to the surface as the head heats. Removing them early keeps the stock clear and free of off-flavors.
