To Boil Mackerel
Ingredients
Directions
Prepare
Clean the mackerel by opening them and removing the insides carefully.
Wash the mackerel and the roes until they are clean.
Soak the mackerel in cold water before boiling.
Boil and serve
In a pot, bring water to a gentle boil and add salt.
Carefully place the mackerel in the boiling water.
Simmer for 15 to 20 minutes, skimming off any scum that rises.
Watch for the tails to split and the eyes to start; remove when done.
Serve on a napkin with fennel or gooseberry sauce and melted butter.

What each ingredient does
- Mackerel
- Forms the main body of the dish, cooking through in gently simmering water to become flaky and tender.
- Fennel or gooseberry sauce
- Adds a sharp, aromatic contrast that cuts through the richness of the oily fish.
- Plain melted butter
- Adds richness and moisture to the mild, lean-to-oily flesh of the boiled fish.
The step that matters
Simmer gently and remove at the right moment. A rolling boil breaks up the delicate flesh and can split the skin, while overcooking dries the fish. Gentle simmering cooks it evenly, and removing it as soon as it flakes keeps it moist.
