Why it works: Parsley and basil match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 2,351 recipes. Both carry myristicin, which smells spice, warm. The science ↓
Mock Turtle Soup
Ingredients
Directions
Prepare the head
Parboil the divided calf's head and cut the meat into small pieces.
Break the bones and boil them in beef broth.
Make the soup
Fry shallots in butter, add flour to thicken, and stir it in.
Skim carefully while it boils, then add the white wine.
Let it simmer until the meat is tender.
Add chives, parsley, basil, salt, cayenne, soy sauce, and mushroom ketchup to taste, and boil for 10 minutes.
Serve
Squeeze lemon juice into a tureen, pour the soup over it, and serve with force meat balls.

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 meat and gelatinous body of the soup once simmered until tender.
- Beef broth
- Forms the savoury liquid base in which the bones and meat cook.
- Butter
- Carries the frying of the aromatics and adds richness to the soup.
- Flour
- Thickens the soup slightly as it cooks, giving it a fuller body.
- White wine
- Adds acidity and aromatic depth to the broth.
- Lemon juice
- Adds bright acidity that lifts the rich flavour of the soup.
The step that matters
Skim carefully while it boils. Foam and fat rising from the meat and bones can make the soup cloudy and greasy, so removing them keeps the broth clear and clean-tasting.
