Why it works: Potato and leek work together. They rank in the top 6% of all ingredient pairs, and cooks put them together in 30 recipes. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓
Codfish and Potatoes-bouillabaisse Op Cod
Ingredients
Directions
Prepare the broth
Melt the butter in a saucepan over medium heat.
Add the chopped leeks or onion and cook until golden, but not burnt.
Pour in the quart of water, add the bunch of herbs, and the saffron tied in muslin.
Add the peeled potatoes and bring to a boil.
Cook and serve
Once the potatoes are nearly cooked, cut the cod into slices and add to the pot.
Cook slowly for 20 minutes, then remove the fish and place it on a hot dish with the potatoes around it.
Season the broth, bring it to a boil, and strain it over slices of bread in a hot dish.
Serve with the fish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Murray cod
- Forms the main body of the dish, flaking into tender pieces as it cooks gently in the broth.
- Potatoes
- Add starch and body, thickening the broth slightly and giving the dish a substantial texture.
- Leeks or onion
- Sweeten and build a savoury base when cooked gently in butter until golden.
- Butter
- Carries the aromatics and adds richness and flavour to the broth.
- Saffron
- Contributes a distinctive aroma and golden colour to the broth.
The step that matters
Cooking the cod in the broth. Add the fish only when the potatoes are nearly cooked and simmer gently. Fish proteins set and toughen with prolonged or vigorous heat, so gentle cooking keeps the slices moist and tender.
Swap the saffron
How well each one fits the dish's main ingredients (potato, leek, butter):
- Thymefits better
- Parsleyfits better
- Capersfits better
- Saffronthe original
Fit is the average pairing score against potato, leek, butter. Candidates are from the same food group and used in at least 100 recipes.
