Strudel dough recipe is a must in every Austrian home and in yours too if you love the flaky but firm consistency of a proper apple Strudel. Follow each step carefully if you make this for the first time. It's important that you add your egg and oil and these things make the dough stretchable. The whole purpose of a proper Strudel dough is its flexibility and the fact that when rolled out super thin to create the delicate but strong layer, it can be wrapped around the heavy filling whiteout breaking apart. See below the recipe for filling ideas and serving instructions.
