Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Softens and browns during frying, adding sweetness and savoury depth to the base.
- Butter
- Carries flavour and browns the fish and onions, and with flour thickens the stew.
- Curry powder
- Supplies the dish's main spiced aroma when stirred into the milk.
- Milk
- Adds creaminess and a mild, smooth body to the sauce.
- White stock
- Provides the main liquid that becomes the body of the stew.
The step that matters
Add the butter-flour thickening to the stock smoothly. Flour thickens only when its starch is evenly dispersed and heated. Mixing it in fully before simmering prevents lumps and gives a smooth, consistently thick sauce.
Swap the onion
How well each one fits the dish's main ingredients (butter, milk, pepper):
- Potatofits better
- Capsicumfits better
- Tomatofits about as well
- Onionthe original
Fit is the average pairing score against butter, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
