The oldest strudel recipes (a Millirahmstrudel and a turnip strudel) are from 1696, in a handwritten cookbook at the Wienbibliothek im Rathaus (formerly Wiener Stadtbibliothek). The pastry is probably descended from similar pastries such as börek and baklava.
Traditional strudel pastry differs from puff pastry in that it is very elastic. It is made from flour with a high gluten content, water, oil and salt, with no sugar added. The dough is worked vigorously, rested, and then rolled out and stretched by hand very thinly with the help of a clean linen tea towel or kitchen paper. There are numerous techniques for manually pulling strudel dough. One method is to roll the dough thin before laying it over the back of the hands and drawing it thin by pulling the hands apart from one another. Purists say that it should be so thin that you can read a newspaper through it. A legend has it that the Austrian Emperor’s perfectionist cook decreed that it should be possible to read a love letter through it. The thin dough is laid out on a tea towel, and the filling is spread on it. The dough with the filling on top is rolled up carefully with the help of the tea towel and baked in the oven.
The best-known strudels are apple strudel (Apfelstrudel in German) and Topfenstrudel (with sweet soft quark cheese, in Austrian German Topfen), followed by the Millirahmstrudel (milk-cream strudel, Milchrahmstrudel). Other strudel types include sour cherry (Weichselstrudel), sweet cherry, nut filled (Nussstrudel), apricot strudel, plum strudel, poppy seed strudel (Mohnstrudel), rhubarb strudel and raisin strudel. There are also savoury strudels incorporating spinach, cabbage, potato, pumpkin, and sauerkraut, and versions containing meat fillings such as the Lungenstrudel or Fleischstrudel.
