Ingredients
Directions
Make the soup
Heat the butter and fry the onions until they are transparent.
Stir in the flour and cook until the flour is golden brown, taking care that no lumps form.
Add crushed mint leaves, salt, pepper, and walnuts, and fry for a few minutes longer.
Add 5 cups of water and sugar to taste, bring to a boil, and simmer for 10 minutes.
Serve
Serve hot with toasted naans.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Soften and sweeten as they cook, forming the savory base of the soup.
- Butter
- Carries the frying of the onions and adds richness and flavor.
- Flour
- Browns and thickens the liquid, giving the soup body.
- Walnuts
- Add nutty flavor and a creamy, slightly thickening texture when cooked.
- Mint leaves
- Contribute a fresh, aromatic herbal flavor to the soup.
The step that matters
Cooking the flour until golden brown. Flour must be stirred constantly over heat so it browns evenly without lumps; if it is undercooked or left to clump, it tastes raw and the soup becomes grainy and uneven.
Swap the mint
How well each one fits the dish's main ingredients (onion, butter, flour, walnut, sugar, pepper):
- Cinnamonfits better
- Nutmegfits better
- Parsleyfits better
- Mintthe original
Fit is the average pairing score against onion, butter, flour, walnut, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
