Why it works: Parsley and carrot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Brown Rabbit Soup
Ingredients
Directions
Prepare
Flour and lightly fry the rabbit joints.
Add the fried onions and pour in the boiling water.
Stir in the salt, skimming off any scum that rises.
Add the parsley, carrots, and peppercorns.
Simmer and finish
Boil gently for 5 to 5.5 hours.
Taste and add more salt if needed.
Strain the soup and let it cool to skim off the fat.
Reheat the soup and serve with fried bread.
Optionally, thicken with rice flour or wheaten flour and add mushroom catsup or sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rabbit
- Provides the meat and rich flavour that form the body of the soup.
- Flour
- Coats the rabbit joints so they brown lightly and help thicken the soup.
- Onions
- Fried to a clear brown, they add sweetness and deep savoury colour to the broth.
- Carrots
- Release natural sweetness and body into the long-simmered broth.
The step that matters
Skimming the scum and the fat. Scum rising at the start and fat left after cooling both cloud the broth and taste greasy. Skimming early and chilling the strained soup lets the fat set on top so it can be removed cleanly.
Swap the onion
How well each one fits the dish's main ingredients (rabbit, flour, parsley, carrot, bread, rice, mushroom):

- Onionthe original
Fit is the average pairing score against rabbit, flour, parsley, carrot, bread, rice, mushroom. Candidates are from the same food group and used in at least 100 recipes.
