Make a shortcrust pastry from flour, an egg, salt, butter and baking powder. Leave in the refrigerator for half an hour and then roll out and place in a greased springform pan. Alternatively, you can of course buy the dough ready-made.
Cut the ham and spread it on the dough. Whisk the remaining eggs, add the sour cream and Emmental cheese and stir. Season with salt and paprika powder. Pour the cheese mixture on the ham. Bake the quiche at 175 ° C - 200 ° C for approx. 25 - 35 minutes.
