Mackerel Fillets
Ingredients
Directions
Poach
Place the mackerel fillets flat in a wide stewpan or saucepan.
Cover the fillets with cold water and add salt and parsley.
Bring the water to a slow boil, skimming off any scum.
Simmer for 2-3 minutes, then check if the fillets are done by testing with a fork.
Carefully lift the fillets out with a slotted spoon and drain.
Serve
Serve hot with butter and parsley, or remove the skin and pour Maitre d’ Hotel sauce over them.

What each ingredient does
- Mackerel fillets
- The main protein; gently poaching firms and flakes the flesh without toughening it.
- Butter
- Adds richness and a silky mouthfeel to the hot fish when served.
The step that matters
Simmering gently after the slow boil. Once the water reaches a slow boil, keeping it at a gentle simmer for only 2-3 minutes cooks the fish through while keeping it moist. Vigorous boiling would break the delicate fillets apart and toughen the flesh.
