these swirls/rolls are made like this: in a large bowl mix 300g flour, 1/4 tsp salt, 35g sugar. make a well in the middle. crumble 20g fresh yeast into the well, sprinkle a knife tip of sugar on it and disolve the yeast in 150ml lukewarm milk. let it stand for a few minutes, until the yeast-milk-mix becomes bubbly. add 70g cold butter, cut in smaller chunks. knead well until the dough comes together nicely. cover with a dish towel and let it rise on a warm place for at least 30 minutes. meanwhile prepare the filling: chop 30g of pistachios, grate one large apple. mix together with 3tbsp ground almonds, 2tbsp sugar and 3tbsp creme fraiche. when the dough is risen, knead again for a few minutes and then roll it out to a rectangle (approximately 25 x 45 cm). brush with 3tbsp of melted butter. then spread the filling on it. roll it up and cut in slices (about 3cm wide). put the rolls on a baking tray lined with parchment paper, cover again with a towel and let them rise for another 30 minutes. brush with 1tbsp melted butter mixed with 1 tbsp milk (which i used) or 1 egg yolk mixed with 1 tbsp milk. bake at 180° for 20 minutes or until golden brown. i like these rolls especially because they are very fluffy, and the filling is moist and not to sweet.
