Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Is the main protein, which firms and turns opaque as it cooks through in the poaching liquid.
- Leeks
- Add mild aromatic sweetness and flavour to the poaching liquid, which is carried into the fish.
- Onion
- Adds savoury aromatic depth to the poaching liquid as it softens and releases its flavour.
- Hollandaise sauce
- Its butter and egg emulsion adds richness and fat that contrasts with the lean, delicate fish.
The step that matters
Simmer gently until the fish separates easily from the bone. Boiling vigorously toughens the delicate muscle fibres and can break the fish apart. Gentle simmering cooks it evenly, and the flesh separates from the bone when it is fully cooked.
