Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Browns in butter to build a sweet, savoury flavour base for the sauce.
- Butter
- Carries the flavours and gives the sauce its rich, fatty body.
- Curry powder
- Adds warm, aromatic spice flavour to the sauce.
- Pickle vinegar
- Adds sharp acidity that brightens the rich butter.
- Pickles
- Add tangy flavour and a bit of crunch to the finished sauce.
The step that matters
Fry the onion until brown. Browning the onion in butter develops deep, sweet flavour through caramelisation. Taking it too far turns it bitter, so watch it closely and remove it once it is evenly browned.
