Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Rabbit Soup
Ingredients
Directions
Prepare the broth
Wash the rabbit well and cut it into small joints.
Put the rabbit, cold water, sliced onions, and cut-up ham into a saucepan. Season with pepper and salt.
Bring to a boil and skim off any foam.
Simmer gently for three hours.
Strain and finish
Strain the soup and carefully remove all fat.
Return the soup to the saucepan. If you want it unthickened, heat it and stir in a teaspoon of chopped parsley before serving.
To thicken, blend the flour with the milk and strain it into the soup. Stir until it boils and cook for five minutes.
Season to taste and serve with diced toasted bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rabbit
- Provides the main meat and flavour that gives the soup its body.
- Ham or pork
- Adds savoury, salty flavour to the broth as it simmers.
- Onions
- Contribute sweetness and aroma to the broth as they cook down.
- Milk
- Adds richness and softness to the soup when blended into the thickening.
- Flour or ground rice
- Thickens the soup as it boils, giving it a smoother, heavier texture.
The step that matters
Stir the thickening as it boils. Flour or ground rice mixed with milk must be blended smooth and stirred while the soup comes to a boil, or it can clump and stay floury. Cooking it for the full time lets the starch swell and fully thicken the soup.
Swap the onion
How well each one fits the dish's main ingredients (rabbit, ham, milk, flour, pepper, parsley, bread):
- Shallotfits better

Fit is the average pairing score against rabbit, ham, milk, flour, pepper, parsley, bread. Candidates are from the same food group and used in at least 100 recipes.
