Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓

Ingredients
Directions
Make the broth
Chop the onions and brown them in butter in a stew-pan.
Add the fish pieces to the pan.
Pour in the olive oil, garlic, bay leaf, lemon slices, tomatoes, saffron, and lemon juice.

Boil for 10 to 20 minutes, skimming carefully.
Finish and serve
Before serving, stir in the chopped parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Provides the main protein and flavour, releasing savour into the broth as it cooks.
- Olive oil
- Carries fat-soluble aroma compounds from the garlic, bay and saffron into the broth.
- Tomatoes
- Add acidity and body, helping build a fuller-flavoured broth.
- Onions
- Browning in butter builds sweetness and a deeper savoury base.
- Saffron
- Adds distinctive aroma and a golden colour to the broth.
The step that matters
Skimming during the boil. Skimming removes coagulated proteins and fat that rise to the surface, keeping the broth clear and free of scum. Boiling hard too long can break up the delicate fish, so the timing matters.
Swap the clove
How well each one fits the dish's main ingredients (onion, butter, fish, olive, garlic, lemon, tomato):
- Thymefits better
- Parsleyfits better
- Capersfits better
- Clovethe original
Fit is the average pairing score against onion, butter, fish, olive, garlic, lemon, tomato. Candidates are from the same food group and used in at least 100 recipes.
