Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. 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 bacon into a saucepan. Season with pepper and coarse sea salt.
Bring to a boil and skim off any foam.
Simmer gently for three hours.
Strain the soup and carefully remove all fat.
Return the soup to the saucepan.
Thicken and serve
To thicken, blend the flour with the milk and strain it into the soup.
Stir until it boils.
Cook for five minutes.
Season to taste and serve with diced toasted bread.
If you want it unthickened, heat it and stir in 1 teaspoon of chopped parsley before serving.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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 flavour that the broth is built on.
- Onions
- Add sweetness and aroma to the broth as it simmers.
- Flour
- Thickens the soup when blended with milk and stirred in to boil.
- Milk
- Mixed with flour to give the thickened soup a creamier body.
The step that matters
Skimming the foam after boiling. Foam that rises at the start carries impurities and fat that can cloud the broth and taste bitter, so it should be removed before simmering.
Swap the onion
How well each one fits the dish's main ingredients (rabbit, ham, milk, flour, pepper):
- Mustardfits better
- Capsicumfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against rabbit, ham, milk, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
