What each ingredient does

John dory fish
Is the main protein, which turns opaque and firm as it cooks.
Butter
Adds richness and fat that complements the mild, delicate fish.
Lemon
Adds acidity that brightens the flavour of the mild fish.

The step that matters

Gently place the fish in the boiling water. Dropping fish into water that is still churning can break the flesh apart. Lowering it in gently keeps the fish intact while it sets.
