Step 1

For the strudel dough, whisk the oil with the egg in a bowl, add vinegar and salt, then alternately stir in water and flour. Stir or beat with a wooden spoon until smooth.

Step 2

Beat the dough several times on a wooden board or another surface (so to speak "throw it on"), so that it gets small bubbles. Cut the dough into thirds and form or roll it into smooth balls with your hands. Coat the dough balls with some oil so that they do not dry out. Put them on a board or a big plate, cover them with a bowl and let them rest for about 30 minutes.

Step 3

Meanwhile, for the filling, melt the butter in a pan and add as many breadcrumbs as the butter absorbs. Let it cool down a little. Wash and peel the apples and cut them into small pieces.

Step 4

Dust the work surface with some flour. Take a ball of dough, first roll it out a little with the rolling pin and then spread it out in the air with your hands over both backs of your hands, making it bigger. Important: Take off the rings!

Step 5

Place a kitchen towel on the work surface, place the strudel dough on top and pull carefully with your fingers along the edges to the right size. The result should be a rectangle almost as big as your baking tray. The dough has the perfect "thickness" when it is wafer-thin, i.e. when you can see the kitchen towel shimmering through, but it does not yet have any holes or the like. But if there should be a few small holes in it, that's not too bad.

Step 6

Cover the dough with about one-third of the butter and breadcrumbs mixture and one-third of the apples. Leave one edge free. Sprinkle cinnamon sugar, raisins and almond slivers over it as you like.

Step 7

Fold the covered dough sheet in at the short sides so that nothing can run out. Use the kitchen towel to roll up the long sides into a strudel. Place the strudel with the cloth on a baking sheet covered with baking paper. The seam (where the ends overlap) should be on the bottom.

Step 8

Whisk the egg yolk with a fork to coat the strudel. Brush the first strudel. Preheat oven to 360°F / 180 °C degrees. Then repeat all steps with the two remaining dough balls and coat the strudel at the end. The 3 strudels fit closely together on a large baking tray.

Step 9

Bake the apple strudels for about 40 minutes until the surface is golden brown. Dust with powdered sugar and enjoy pure or together with vanilla sauce or vanilla ice cream.
