Why it works: Allspice and clove match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 7,874 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Brown Soup
Ingredients
Directions
Prepare
Cut the bacon into strips and slice the onions.
Make the soup
In a soup pot, melt the butter with the bacon and onions, simmering until browned but not scorched.
Mix the browned flour with cold water until smooth, then add to the pot and stir until very hot.
Remove the fat from the top of the mutton liquor and pour it into the pot, adding pepper and parsley.
Gradually stir in the liquid to avoid lumps, cover, and simmer at the back of the stove for two hours.
Serve
Strain the soup into a tureen before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bacon
- Adds savoury fat and meaty flavour as it browns with the onions.
- Butter
- Carries the onions and bacon and helps them brown evenly.
- Browned flour
- Thickens the soup and adds a deeper, toasted flavour.
- Mutton liquor
- Forms the main savoury liquid that gives the soup its body and flavour.
The step that matters
Simmering the onions and bacon until browned but not scorched. Browning builds deep flavour through the Maillard reaction, but scorched fat and sugars turn bitter and can taint the whole pot.
Swap the onion
How well each one fits the dish's main ingredients (butter, allspice, clove, flour, mutton, pepper, parsley):
- Shallotfits better
- Carrotfits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against butter, allspice, clove, flour, mutton, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
