Rub the mackerel with
mustard and grill them, ten minutes on each side. In the mean time,
add half a cup of water and the sugar to the gooseberries (keep a few
behind for decoration) and bring to the boil. Cook 10 minutes on low
heat, stir until they are mashed and stir in the cream and the nutmeg.
Pour the sauce on top and garnish with gooseberries.
In
French, gooseberries
are called "groseilles à macquereau", so mackerel and gooseberries
may have been together already long ago.
