The Original "Quiche Lorraine" was a savoury, open-faced pastry dish with a filling consisting of an egg and cream custard with smoked bacon.
It was only later that cheese was added, meat, fish or / and vegetables. Add onions and you have Quiche Alsacienne.
The bottom crust was originally made from bread dough, but it has evolved into a short-crust or puff pastry crust.
Although quiche is now a classic dish of French cuisine, quiche actually originated in Germany, in the medieval kingdom of Lothringer, under German rule, and which the French later renamed Lorraine ( how could France lets Lorraine and its quiche in Germany ! This recipe deserved a battle :)
It is the most simple and versatile recipe that I cook all the time, you can eat it hot, warm, cold with a salad, add any vegetables you want, like asparagus, tomatoes, leeks, broccoli etc... Easy to bring to parties, picnics and children love it.
