For the quince strudel, prepare a strudel dough from the dough ingredients. You can find a recipe for it here.
For the filling, rub the quinces with a tea towel to remove the fluff.
Then wash the fruit, cut into quarters and remove the blossom end and the stem. Cut out the core, removing also the peel and hard parts under the core.
Cut the fruit into slices and put them in a pot. Cover with water, add the sugar and steam the quinces until firm to the bite.
Strain and let drain well.
Draw out the strudel dough (on a cloth) and spread with butter. Sprinkle with breadcrumbs. Spread the quinces on top and sprinkle with sugar.
Roll up the strudel with the help of the cloth.
Brush the quince strudel with butter and bake in the oven on the middle rack at about 170 °c for about 20 minutes until it is nice and golden.
Serve sprinkled with powdered sugar.
