Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Mullagatawny Soup
Ingredients
Directions
Make the broth
In a stewpan, combine veal trimmings, black peppercorns, allspice, and water. Bring to a boil, skim, and simmer for 1.5 hours. Strain the broth.
Brown and simmer
In a separate pan, fry the veal pieces and onions in butter until browned.
Add the strained broth to the veal and onions, skim, and simmer for 30 minutes.
Thicken and finish
Mix curry powder, flour, salt, and enough cold water to make a batter. Stir this into the soup.
Simmer for an additional 10 minutes before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal
- Provides meat flavour and body to the broth as it simmers and browns.
- Onions
- Soften and brown in butter, adding sweetness and depth to the soup.
- Curry powder
- Supplies the spiced aroma that defines the soup.
- Flour
- Thickens the soup slightly when stirred in as a batter.
The step that matters
Stirring in the flour batter. Flour mixed with cold water must be fully smooth before it goes into hot soup; added lumpy or dry, it clumps and does not thicken evenly. Simmering afterward cooks out the raw flour taste and lets the starch thicken the broth.
Swap the allspice
How well each one fits the dish's main ingredients (veal, onion, flour, butter):
- Capersfits better
- Garlicfits better
- Parsleyfits better
- Allspicethe original
Fit is the average pairing score against veal, onion, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
