Why it works: Onion and tomato are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 20,633 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Curried Oysters
Ingredients
Directions
Prepare the oysters

Make the curry
Slice the onion.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main protein and briny flavour that the curry sauce surrounds.
- Butter
- Carries the curry spices and browns the onion, adding richness to the sauce.
- Onion
- Browns in butter to build a sweet, savoury base for the sauce.
- Curry powder
- Supplies the warm spiced aroma that defines the dish.
The step that matters
Frying the onion until rich brown. Browning caramelises the onion's sugars and develops deep, savoury flavour. Pale onion gives a flat, sharp-tasting base, while over-darkened onion turns bitter.
Swap the apple
How well each one fits the dish's main ingredients (oyster, butter, onion, coconut, flour, tomato, lemon):
- Avocadofits better
- Limefits better
