Some important ingredients for German apple strudel recipes are apples, pastry dough, butter, sugar and cinnamon. Other ingredients that are not critical to the strudel, but add to the recipes, include pecans or walnuts and raisins.
To make the Food Network's version of German apple strudel, soak 1/2 cup of golden raisins in 1/2 cup of apple juice for 15 minutes. Meanwhile, add 5 peeled, cored and sliced Granny Smith apples, 1/2 cup of brown sugar and 1/2 cup of water to a saucepan, and bring everything to a simmer until the apples turn soft. In another bowl, mix together 1 tablespoon of cinnamon, 1 tablespoon of sugar and 1/4 cup of chopped pecans.
Next, lay 7 phyllo dough sheets out one at a time on top of each other, and brush each with melted butter, and sprinkle with the cinnamon sugar mixture. On top of the pastry sheets, pour the apple and raisin mixtures, and roll the pastry around it to form a log. Brush the top with butter, sprinkle it with brown sugar, and bake it at 350 degrees Fahrenheit for 35 to 40 minutes.
Another recipes calls for combining 3 sliced Granny Smith apples and 1 shredded Granny Smith apple in a bowl with 1 cup of brown sugar and 1 cup of golden raisins.
