Why it works: Parsley and turnip match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 2,842 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Mock Turtle or Calf's Head Soup
Ingredients
Directions
Prepare the stock
Clean, wash, and soak a large calf's head; put it in a pot with a knuckle of veal, a hock of ham, or a few slices of bacon, reserving veal for meatballs.
Add enough water to cover the head and other meats.
Boil slowly for four hours, skimming carefully.
Make the soup
Add six sliced potatoes, three sliced turnips, equal parts of parsley, sweet marjoram, and sweet basil, chopped finely, plus pepper and salt to taste.
One hour before serving, make about two dozen small force-meat balls from minced veal and beef suet, seasoning with pepper, salt, sweet herbs, grated lemon peel, powdered nutmeg, and mace; add beaten egg yolk, flour, and fry in butter.
Remove the head and other meats from the soup, cut the meat from the head into small pieces, and return it to the soup.
When the soup is nearly done, stir in half a pint of Madeira.
Prepare at least a dozen egg-balls by mixing yolks of hard-boiled eggs with flour and raw egg yolk, shaping them into marbles.
Add the egg-balls and a squeeze of lemon juice to the soup, let it boil slowly again, then serve in a tureen.

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)
- Provides gelatin and meat, giving the soup its body and rich, savory character.
- Potatoes
- Break down during long simmering to thicken the soup and add body.
- Madeira
- Adds a sweet, fortified wine aroma and depth to the finished soup.
- Egg yolks (in the method)
- Bind the force-meat and egg-balls, giving them a tender, set texture.
The step that matters
Skimming during the four-hour boil. Long simmering releases foam and fat from the head and meats; skimming carefully keeps the stock clear and free of greasy, off-flavored residue.
Swap the turnip
