Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the dish and soak up the sauce as they stew.
- Onion
- Softens and sweetens as it fries in butter, forming the base flavour.
- Butter
- Carries the curry powder and adds richness while frying the onion.
- Curry powder
- Provides the spiced aroma and colour that defines the dish.
- Stock
- Moistens the pan so the potatoes stew into a saucy coating.
- Lemon juice
- Adds a bright acidity that balances the richness of the butter and spices.
The step that matters
Stirring the curry powder into the butter and onion. Curry powder contains fat-soluble aromatic compounds that bloom when briefly fried in butter. Adding it to a dry or overly hot pan can scorch it, giving a bitter taste.
