Directions

1. For the pastry, pour out the flour and salt on a clean surface, making a well in the center. Cut up the butter into cubes and place in the well, along with the egg yolk, sugar and water. Mix it with your fingers, eventually forming it into a ball, and knead. Add more water if too dry and more flour if too sticky. Knead well for a few minutes until smooth. Wrap the ball of dough in plastic wrap and chill for 30 minutes.
2. Line a baking sheet with parchment paper and pre-heat the oven to 400°F.
3. Prepare the filling by quartering and pitting the nectarines (without peeling). Cut into slices, but not too thin. Combine in a bowl with the blueberries, flour and sugar, and mix well.
