Why it works: Parsley and spinach match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 1,025 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Pigeon Soup
Ingredients
Directions
Make the broth
Cut up 2 pigeons and place them in a large pot with 4 quarts of cold water, along with the necks, livers, and pinions of the remaining pigeons.
Simmer and boil until the substance is extracted, then strain the soup.
Finish the soup
Return the strained soup to the pot and add the chopped parsley, chopped spinach, cream, and boiled bread crumbs.
Truss and season the remaining pigeons with coarse sea salt and a little mace.
Boil the seasoned pigeons in the soup until they are tender.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pigeons
- Provide the main meat and flavour, with the bodies and giblets enriching the broth.
- Cream
- Adds richness and a smooth, silky body to the finished soup.
- Bread crumbs
- Thicken the soup slightly and give it body as they absorb liquid.
- Spinach
- Adds soft texture and a mild vegetable flavour, with some thickening as it cooks.
The step that matters
Simmer and strain the broth. Gentle simmering extracts flavour and gelatin from the birds without a hard boil, which would cloud the broth and toughen the meat. Straining removes solids so the soup stays clear and smooth.
Swap the mace
How well each one fits the dish's main ingredients (parsley, spinach, cream, bread):
- Nutmegfits better
- Capersfits better
- Garlicfits better
- Macethe original
Fit is the average pairing score against parsley, spinach, cream, bread. Candidates are from the same food group and used in at least 100 recipes.
