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
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Brown the rabbit
Dip the rabbit pieces in flour and fry in butter until browned.
Add the fried onions to the pot.
Simmer the soup
Pour boiling water over the rabbit and add salt.
Skim frequently until the broth is clear.
Add parsley, carrots, and whole peppercorns.
Boil gently for about 6 hours.
Adjust seasoning if necessary.
Strain and serve
Strain the soup and let it cool, then skim off the fat.
Reheat before serving and serve with croutons.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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 pieces so they brown well and help thicken the broth.
- Butter
- Fat for frying that browns the rabbit and adds richness.
- Onions
- Fried brown first, adding deep savory flavor to the broth.
- Carrots
- Add natural sweetness and body to the long-simmered broth.
The step that matters
Skim frequently until the broth is clear. Skimming foam and impurities as the broth first simmers keeps it clear and clean-tasting. Skimming again after cooling removes the solidified fat, which otherwise makes the soup greasy.
Swap the onion
How well each one fits the dish's main ingredients (rabbit, flour, butter, parsley, carrot):
- Shallotfits better
- Parsnipfits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against rabbit, flour, butter, parsley, carrot. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
