- 1 3/4 tablespoons corn starch

Instructions
Make the dough:
- Heat the milk until pleasantly warm to the touch (it's best to check its temperature with a thermometer, it should be 100-110°F (38-43°C)). The milk can't be too cold or too hot or the yeast won't work.1/3 cup + 1 tablespoon (95g) milk
- Add the milk to a small bowl, add the yeast, and 1/2 tablespoon of sugar. Stir together and set aside to proof for 10 minutes. After this time, the yeast should be foamy, if it's not, start over. It is not necessary to proof instant yeast, but I've found that when doing this, the dough rises better and faster and also, you can be sure that your yeast is working properly.1 packet instant yeast
- In the meantime, you can make the crumble: Add all the ingredients for the crumble to a medium bowl and work the butter into the dry ingredients with your fingers until the mixture resembles coarse crumbs. Place the bowl in the fridge.3 tablespoons (42g) cold butter, 1/2 cup (62g) all-purpose flour, 3 tablespoons granulated sugar, big pinch of salt
- To a medium/large mixing bowl, add the yeast mixture, flour, salt, and the remaining sugar (2 1/2 Tbsp). Stir together. Add the egg, egg yolk, and vanilla. Knead the dough by hand or with a stand mixer fitter with a paddle attachment until it comes together.2 1/4 cups (280g) all-purpose flour, 1/4 teaspoon fine sea salt, 1 large egg, 1 large egg yolk, 2 teaspoons vanilla extract
- Slowly add the soft butter, tablespoon after tablespoon, adding the next one when the previous one has been incorporated into the dough. Knead the dough for a couple more minutes until smooth.5 tablespoons (72g) soft butter
First rise:
- Cover the bowl with the dough with plastic foil and put in a warm place to rise until it doubles its volume, about 1 hour (I'm putting it in a turned-off oven with a light on).
Shape the buns:
- When the dough is risen, prepare the blueberries. Wash them and thoroughly pat dry with paper towels then combine with corn starch and powdered sugar.13 ounces (365g) blueberries, 1 3/4 tablespoons corn starch, 2 tablespoons powdered sugar
- Transfer the dough to a very lightly floured counter or a rolling mat. Divide the dough into 6 equal parts.
- Flatten each part of the dough, making sure the middle is not thinner than the edges. Top with the blueberry filling, making sure to scoop also the dry ingredients. Pinch all the edges together until the blueberries are enclosed in the dough. Make sure there are no gaps and the dough is well sealed.
- Place the buns on a baking sheet lined with parchment paper seam-side down.
Second rise:
- Cover the baking sheet with a kitchen towel and let the buns rise for 20 minutes.
- Set the oven to 375°F (190°C).
- After 20 minutes, prepare the egg wash: in a small bowl, whisk together the egg and water.1 egg, 1 tablespoons water
- Brush the buns with the egg wash and top with the crumble.
Bake the buns:
- Bake until browned, about 23-24 minutes.
- Let cool slightly then enjoy (you can eat them slightly warm)!
Notes
- These blueberry buns are not overly sweet. If you'd like them sweeted, sprinkle some granulated sugar on top of the blueberries when you are filling the dough with them or make icing sugar to pour on top of the baked buns.
- How to correctly measure flour: I’m using the “spoon and level method” so 1 cup of flour in my recipes weighs 125g. Fluff the flour by stirring it in the bag/flour container with a spoon. Spoon the flour and sprinkle it into your measuring cup. Sweep off the excess flour with the back of a knife. Too much flour added to pancake batter will result in dry and dense pancakes. I recommend using a digital scale for perfect and consistent results.
