Swedish Cinnamon Buns with Yeast-Ripened Dough

Method

1. In a large bowl, combine flour, sugar, salt, and yeast.
2. Add the cold cubed butter and mix until the texture resembles coarse crumbs.
3. In a separate bowl, whisk together warm milk, egg, and a little water to activate the yeast.
4. Gradually add the wet ingredients to the dry mixture and knead until a smooth dough forms.
5. Cover the dough and let it rise in a warm place for 2 hours to allow for slow fermentation.
6. Shape the dough into small buns, place on a baking sheet, and let them rise again for 30 minutes.
7. Brush with the egg yolk glaze and sprinkle with cinnamon sugar.
8. Bake at 180°C (350°F) for 15-20 minutes until golden brown.
