Why it works: Beef and mushroom are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,232 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
Pigeon Soup
Ingredients
Directions
Make the stock
Make a strong beef stock, seasoned well.
Clean the pigeons, removing necks, pinions, livers, and gizzards, and add them to the stock.
Cook the soup
Quarter the pigeons and brown them nicely.
Strain the stock and add the pigeons.
Boil until nearly ready, about 30 minutes.
Thicken the soup with flour mixed in a cup of the soup.
Season with nutmeg, lemon juice or vinegar, and mushroom ketchup.
Boil for a few minutes, then serve with the pigeons in the tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pigeons
- Provide the main meat, which becomes tender and flavourful as it simmers in the stock.
- Strong beef stock
- Forms the liquid base and carries most of the soup's savoury flavour.
- Flour
- Thickens the soup as its starch swells when heated in liquid.
- Mushroom ketchup
- Adds savoury, umami depth to the seasoned broth.
- Lemon juice or vinegar
- Adds acidity that brightens and balances the rich stock.
The step that matters
Thicken the soup with flour mixed in a cup of the soup. Flour must be blended into liquid first so its starch disperses evenly; added dry it clumps. Boiling for a few minutes afterward lets the starch swell fully and thicken the soup smoothly.
