Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dal
- Breaks down during simmering to give the soup body and thickness.
- Ghee or dripping
- Fat for frying the vegetables, carrying flavor and aiding browning.
- Cornflour
- Starch that thickens the soup when it is brought to a boil.
- Cow's milk
- Adds creaminess and softness to the finished soup.
- Stale bread
- Soaks up the soup, giving the dish substance and a soft texture.
The step that matters
Stir the cornflour mixture in and boil it briefly. Cornflour must be mixed smooth in cold milk first, then heated, so starch granules swell evenly and thicken without lumps.
Swap the leek
How well each one fits the dish's main ingredients (onion, carrot, ghee, milk, bread, pepper):
- Potatofits better
- Capsicumfits better
- Tomatofits better
- Leekthe original
Fit is the average pairing score against onion, carrot, ghee, milk, bread, pepper. Candidates are from the same food group and used in at least 100 recipes.
