Roll out your sheet of pastry on baking paper in a baking dish, pressing the edges well.
Place an extra sheet of baking paper on top and fill with baking beads or dry beans.
Bake blind for 25 min at 175°C, put the beans in a jar, you can keep reusing them.
Meanwhile, put a knob of butter in a saucepan and let it melt gently.
Place the washed endives around it, season with pepper, salt, and grated nutmeg.
Cover completely with water, place a sheet of baking paper or a lid on top, and let the endive cook gently until all the moisture has evaporated and they are soft. If they are not yet cooked, add more water and let it boil down again.
Now let them color nicely on both sides until they caramelize beautifully.
Place them on kitchen paper, place another kitchen paper on top, and press down to remove moisture from the inside well; otherwise, your quiche will be watery.
Tear the ham into strips and fill the pastry case with it, arranging the baked endive on top.
Cut the cheese into 1 cm cubes and sprinkle over it.
Beat the eggs with cream, pepper, salt, and nutmeg well.
Place your quiche on a rack in your preheated oven and pour the mixture in.
Gently slide it in and bake for 20-25 min until it is set and cooked through.
Serve optionally with a fresh green salad with just some vinegar, pepper, salt, and oil on it.
