Why it works: Onion and carrot are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 21,601 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Mulligatawny Soup
Ingredients
Directions
Make the stock
Make a strong stock by simmering veal trimmings, gristle, bones, and knuckle in 3 quarts of water for several hours.
Make the soup
In a deep stew pan, sauté the veal pieces, sliced onions, and ham in butter until slightly browned.
Stir in the flour and pour the strained stock over the meat mixture.
Simmer gently for 1 hour, skimming off fat as it rises.
Add curry powder, salt, and cayenne, and continue simmering until the veal is thoroughly cooked.
Remove the ham before serving. Optionally, add sautéed carrot, turnip, or apples.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal
- Provides meat flavor and gelatin from the bones and knuckle, giving the soup body.
- Flour
- Thickens the stock so the soup has a fuller, heavier texture.
- Curry powder
- Supplies the spiced, aromatic flavor that defines the soup.
- Onions
- Browned in butter, they add sweetness and savory depth to the base.
- Butter
- Fat for frying that carries flavor and promotes browning of the meat and onions.
The step that matters
Skimming fat during the simmer. Fat rising from the veal and ham can make the soup greasy and dull in flavor, so skimming it as it forms keeps the broth clean-tasting.
Swap the carrot
The recipe marks carrot as optional. How well each one fits the dish's main ingredients (veal, butter, onion, ham, flour):
- Leekfits better
- Shallotfits better
- Chivefits better
- Carrotthe original
Fit is the average pairing score against veal, butter, onion, ham, flour. Candidates are from the same food group and used in at least 100 recipes.
