Why it works: Parsley and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Mock-turtle Souf
Ingredients
Directions
Prepare the head
Clean and wash the calf's head, split it in two, and save the brains.
Boil the head in plenty of water until tender.
Make the soup
In a stew pan, fry the ham, parsley, thyme, leeks, cloves, and black pepper in butter until browned.
Add the boiling water from the head to the stew pan.
Cut the meat from the head into neat square pieces and add to the soup.
Stir in the Madeira and lemon slices, then season with cayenne pepper and salt to taste.
Let it simmer gently for two hours, then skim it clear and serve.
Make the forcemeat balls
For the forcemeat, pour hot water over the brains in a stew pan and heat for a few minutes.
Chop the brains with parsley, salt, pepper, flour, butter, and beaten egg.
Form small balls and drop them into the soup fifteen minutes before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Provides the gelatinous meat and body that give the soup its rich texture.
- Butter
- Carries the aromatics and browns them, building savory flavor at the start of the soup.
- Madeira wine
- Adds sweetness and depth of flavor that rounds out the soup.
- Lemon
- Adds acidity that brightens the rich, heavy broth.
- Egg
- Binds the chopped brains into a forcemeat that holds its shape in the soup.
- Wheat flour
- Thickens the forcemeat mixture so the balls hold together while cooking.
The step that matters
Simmering and skimming the soup. A gentle simmer keeps the broth clear, while a boil would emulsify fat and cloud it. Skimming removes the foam and fat that rise to the surface, so the finished soup stays clear.
Swap the leek
How well each one fits the dish's main ingredients (ham, parsley, thyme, clove, pepper, butter, madeira wine):
- Shallotfits better
- Carrotfits better
- Leekthe original
- Turnipfits about as well
Fit is the average pairing score against ham, parsley, thyme, clove, pepper, butter, madeira wine. Candidates are from the same food group and used in at least 100 recipes.
