Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White fish
- Is the main cooked protein, set gently by simmering rather than boiling.
- Coarse sea salt
- Seasons the poaching water so the fish is flavored as it cooks.
- Butter
- Adds richness and a smooth fat note to the finished fish.
- Hard-boiled eggs
- Add a soft, creamy contrast as a garnish alongside the fish.
The step that matters
Simmer, do not boil, for 30 minutes. At a gentle simmer the fish cooks evenly and stays tender and moist. A rolling boil agitates and toughens the delicate proteins, causing the flesh to break apart and dry out.
