Heat the milk 40 degrees and mix the sugar together with the yeast
into the milk. Wait 5 to 10 minutes until it gets foamy.
Melt the butter and combine the flour, salt, vanilla, 3 egg yolks
with the butter and the yeast-milk mixture.
Knead until you have a smooth dough, by hand roughly 15 minutes, by
machine 5.
Give the dough one hour to grow. After 30 minutes fold it once.
Divide the dough into 16 small balls. Flatten those into small
circles of roughly 10 cm diameter.
Place a handfull of blueberries in the middle and put one teaspoon
of powdered sugar ontop. Use water to wet the boundaries of the circle
and pinch the edges together. Tuck all of the folds underneath and put
on a baking tray.
Bake for 15 minutes at 180 degrees.
Variants
One can make a glaze out of 1.5 tablespoons of lemonjuice, 1.5
tablespoons of water and some powdered sugar. Spread this over the warm
buns.
