Why it works: Onion and barley are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 1,166 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Hare Soup
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the stock
Combine hare, mace, salt, onions, red herring, morels, red wine, and water in a covered pot.
Bake in a 400°F (200°C) oven for 3 hours, or simmer in a boiling water bath for the same time.
Strain the soup into a separate pot.
Prepare the thickening
Boil barley or sago in water until cooked.
Scald the hare's liver in boiling water for 2 minutes.
Rub the liver through a sieve.
Finish the soup
Add the liver, barley or sago, and butter to the soup, stirring gently without boiling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hare
- Provides the main meat and rich flavour as the soup slowly cooks down.
- Red wine
- Adds acidity and depth, helping to balance the rich meat flavour.
- Pearl barley or sago
- Swells during cooking and gives the soup body and a thicker texture.
- Butter
- Adds fat, giving the finished soup a smooth, rounded mouthfeel.
- Liver (in the method)
- Pureed into the soup, it adds richness and helps thicken the broth.
The step that matters
Stirring in the liver without boiling. Liver proteins can curdle and turn grainy when boiled, so the soup should be stirred gently and kept just below a boil once the liver and butter go in.
Swap the mace
How well each one fits the dish's main ingredients (onion, red wine, barley, butter):
- Thymefits better
- Garlicfits better
- Celeryfits better
- Macethe original
Fit is the average pairing score against onion, red wine, barley, butter. Candidates are from the same food group and used in at least 100 recipes.
