Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Mock Turtle Soup, of Calf's Head
Ingredients
Directions
Prepare the calf's head
Scald a well‑cleansed calf's head.
Remove the brain.
Tie the head up in a cloth.
Boil for an hour, or until the meat will easily slip from the bone.
Take out the head and save the broth.
Cut the head into small square pieces.
Throw the pieces into cold water.
When cool, put the pieces in a stewpan and cover with some of the broth.
Let it boil until quite tender, then set aside.
Make the soup
In another stewpan melt some butter.
Add a quarter pound of lean ham, cut small, with fine herbs to taste.
Add parsley and one onion.
Add about a pint of the broth.
Let it simmer for two hours.
Dredge in a small quantity of flour.
Add the remainder of the broth.
Add a quarter bottle of Madeira or sherry.
Let all stew quietly for ten minutes.
Rub through a medium sieve.
Add the calf's head.
Season with a very little cayenne pepper, a little salt, the juice of one lemon, and, if desired, a quarter teaspoonful pounded mace and a dessert spoon sugar.
Serve
Add the force meat balls to the soup.
Serve hot after five minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head (in the method)
- Supplies the gelatinous meat and tender pieces that give the soup body.
- Lean ham
- Adds savoury, meaty flavour to the stock as it simmers.
- Butter (in the method)
- Melted fat that carries the flavour of the herbs and onion before the broth is added.
- Flour (in the method)
- A small dredging of flour that thickens the soup slightly as it stews.
- Madeira
- Adds wine acidity and a rich, aromatic sweetness to the finished soup.
- Lemon
- Its juice adds acidity that brightens the rich broth.
The step that matters
Letting the calf's head boil until quite tender. Boiling gently until the meat is fully tender lets collagen break down into gelatin, giving body to the broth. Undercooked meat stays tough and the soup tastes thin.
