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 ↓

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 body of the soup as it simmers for hours.
- Flour
- Coats the rabbit joints so they brown lightly and add savour to the broth.
- Onions
- Frying to clear brown builds deep, sweet savoury flavour in the broth.
- Carrots
- Add sweetness and body to the broth during the long simmer.
- Parsley
- Adds a fresh, herbal aroma to the simmering broth.
The step that matters
Skimming the fat after cooling. Fat that rises as the soup cools solidifies on top, so it can be lifted off cleanly. Skimming while hot leaves greasy droplets in the broth.
Swap the onion
How well each one fits the dish's main ingredients (rabbit, flour, parsley, carrot, bread, rice, mushroom):

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.
