Combine all the ingredients and knead for about ten minutes until you have a nice ball. Place the dough in a bowl, seal tightly with plastic wrap, and let it rise for at least 1 hour in a warm place.
(One hour later) Peel the apples. Remove the bottom half of the core using an apple corer. Cut the core halfway loose by going horizontally through the apple with the tip of a knife. The top centimeter of the core and the stem must remain intact!
Mix the brown sugar, butter, and cinnamon into a thick paste and fill the holes of the cores with it. Push down well.
Preheat the oven to 190 °C.
Take the dough out, sprinkle some flour on the work surface, and divide the dough into four pieces (or five, depending on the number of apples).
Roll each piece out into a round sheet.
Place the apple on it and try to estimate how much dough you need to wrap it completely.
Cut the dough to size, by hand or with a round cutter.
Poke a hole in the center and place it over the stem. Fold the dough neatly closed at the bottom.
Beat the egg yolk with the milk and brush each apple with the mixture for a shiny crust.
Place the apples in a fireproof dish and bake them for 20 to 25 minutes, depending on the size of the apples.
Tips
- The yeast dough needs to rise for an hour!
