Unroll the pie crust and precisely fit it a pie pan. Prick the dough all over with a fork. Then put the pie in the fridge.
Put the thawed spinach in a saucepan over low heat or in a microwave and let them cool.
Meanwhile, mash cheese with a fork in a bowl.
Squeeze the spinach well in your hands to remove any water.
Take out the pie crust from the fridge and spread the spinach on the pie.
Sprinkle raisins and cover with cheese, salt and pepper.
In a bowl, whisk the eggs with the cream, flavor with nutmeg and pour into the pie.
Bake for about 35 min.
Once the pie is baked, remove from the oven and enjoy with a salad.
From experience, to prevent the pie crust collapsing during the cooking, I prefer to put the pie pan with the pie crust into the fridge a few minutes before I add the filling, so the edge of the pie crust hardens.
