Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Sheep's-head Soup
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the head
Remove the brains and tongue from the sheep's head and set aside.
Break the bone of the head.
Wash the head well.
Soak the head in salted water for 30 minutes.
Cover the head with fresh water.
Heat gradually to a boil.
Drain the water to remove any odor.
Make the broth
Add 4 quarts of cold water and the chopped vegetables and herbs.
Boil slowly for 4 hours.
Strain the soup into a bowl.
Let the soup cool until the fat rises.
Return the skimmed broth to the heat.
Season the broth.
Boil briefly.
Stir in the milk mixed with corn starch.
Simmer for 2 minutes.
Make the force-meat balls and serve
Prepare the force-meat balls by mixing the chopped tongue and brains with bread crumbs, salt, pepper, parsley, and the raw egg.
Roll the mixture into small balls.
Dust the balls with flour.
Place the balls on a tin plate.
Bake in a 400°F (200°C) oven until a crust forms.
Place the force-meat balls in a tureen.
Pour the soup over the balls.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sheep's head
- Forms the rich, gelatinous base of the broth as it simmers for hours.
- Eggs
- Binds the force-meat balls so they hold their shape while baking.
- Bread crumbs
- Absorbs moisture and gives the force-meat balls a tender, binding body.
- Milk
- Adds creaminess and mild sweetness to the finished soup.
- Corn starch
- Thickens the milk-enriched broth so it becomes smooth and lightly body-rich.
The step that matters
Stirring the milk and corn starch into the broth. Corn starch needs to be added to hot liquid and kept simmering briefly so it gelatinizes and thickens. Adding it cold or skipping the short simmer leaves the soup thin and can let the milk separate or taste raw.

Fit is the average pairing score against carrot, celery, bread, pepper, parsley, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
