Step-by-step recipe
Preparing the fish
Thaw the mackerel at room temperature, or better, move the frozen fish from the freezer to the fridge the evening before. The fish will thaw perfectly and will not leak.
Fillet the mackerel. Rinse the fish, cut off the head and tail, slit the belly and remove all the innards. Thoroughly remove the black film lining the cavity; it comes off easily with your fingers under cold running water. With a sharp knife, take two fillets off the fish and carefully remove all the large bones and any remaining fins.
Marinating
Rub the fillets with spices. In a mortar, combine 0.5 tsp Provencal herb blend, 1-2 pinches of salt, 3-4 black peppercorns, 1-2 allspice berries and 0.5 tsp coriander seeds. Grind the spices coarsely and sprinkle them over the flesh side of both fillets.
Marinate the fillets in wine. In a ceramic (or plastic) dish of a suitable size, lay a few thinly sliced lemon rounds and put both fillets on them skin side down. Arrange sprigs of fresh herbs: rosemary, thyme and mint. Pour over a mixture of 1 tbsp lemon juice and half a cup of dry white wine (100 ml). Refrigerate the fish to marinate for 1 hour.
Baking in foil
Layer the fillets on the foil. Take the fillets out of the marinade, pat dry with paper towels and brush with olive oil. On a piece of foil, put half of the lemon rounds from the marinade, and on them one fillet skin side down. Finely chop a garlic clove and scatter it over the mackerel, then add all the herbs from the marinade.
Press the second fillet, brushed with oil, on top so that flesh meets flesh. Add the remaining lemon rounds.
Wrap the stacked fillets tightly in foil, preferably in two layers. Pierce the foil with a toothpick in several places; steam will escape through the holes.
Bake the mackerel at 180°C for about 45 mins. Preheat the oven to 180°C, put the package on a baking sheet, preferably ceramic, and place it in the oven. It takes some time for the mackerel to heat up: when a thin stream of steam comes out of the holes in the foil, the mackerel has started to bake. From that moment, bake for another 20 mins.
The cooked fillet is opaque and flakes easily with a fork.
Serving
Before serving, unwrap the foil (carefully, hot steam will escape) and put the mackerel on plates.
Add a lemon quarter to the fish. Mackerel in foil is served with a side of fresh herbs, fresh and pickled vegetables. It goes nicely with baked potatoes.
