Preparation
For the shortcrust pastry
- Mix the flour, baking powder and salt in a bowl.
- Add the butter.
- With a pastry blender or two knives, work the mixture until you get a grainy texture.
- Add the ice water, a little at a time, and mix until you get the right texture.
- Cover the bowl and rest it in the refrigerator for 30 minutes.
For the filling
- Preheat the oven to 230℃ (450℉).
- Peel the apples, cut them into quarters and then slice them thinly. Pour 30 ml (2 tbsp.) of sunflower oil into a skillet and brown the apple slices.
- Add the Sortilège and reduce until evaporated. Let cool and set aside.
- Chop the onions into small pieces.
- Clean the mushrooms and slice finely.
- Sauté the onions and mushrooms with the remaining oil. Add the garlic, the ground turkey, the herbs and the green alder.
- Salt to taste and cook approximately 15 minutes at a medium heat.
- Transfer the preparation into a bowl and let cool. Add the cheese.
- On a floured surface, roll out the dough and line the rectangular mold with it.
- Brush the dough with the ginger mustard. Place the apple slices on the dough. Add the turkey mixture on top of the apples.
- With the rest of the dough, make strips and lay them out diagonally on the preparation to make a grid. Beat the egg with some water and brush it over the dough.
- Bake for between 15 to 20 minutes until the dough is golden brown.
