Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Forms the main body of the dish, cooking into moist, flaky flesh in the gentle poaching liquid.
- Coarse sea salt
- Seasons the court-bouillon so the fish is flavoured as it poaches.
- Onion
- Adds aromatic sweetness and depth to the court-bouillon.
- Leek
- Contributes mild, savoury aroma to the poaching liquid.
The step that matters
Remove any scum from the court-bouillon. Impurities that rise to the surface of the liquid can cloud the broth and mar the fish's appearance and flavour. Skimming before the fish goes in keeps the liquid clear, and the gentle simmer keeps the salmon tender rather than tough and broken.
Swap the onion
