Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Provides the main meat, which becomes tender as it simmers in the sauce.
- Butter
- Carries the onion and curry flavour and adds richness to the sauce.
- Onions
- Fried until browned, they add sweetness and depth to the sauce.
- Curry powder
- Supplies the spiced aroma and flavour that define the dish.
- Stock
- Forms the liquid base of the sauce and carries the flavours through the dish.
The step that matters
Stirring the curry powder into the butter. Curry powder must be added gradually so it blends smoothly into the fat and liquid without lumps. Adding it all at once can leave clumps that stay in the sauce.
