Preheat oven to 375°F. Line a cookie sheet with parchment paper.

Cut puff pastry into 8 squares.

Cut each square into two triangles for a total of 16 triangles.

Using a paring knife, cut out small triangles from the center of 8 of the puff pastry triangles.

Whisk cheese, sugar, lemon zest and egg yolk together.

Fill each triangle with 1 teaspoon cherry preserves and 1 tablespoon cheese mixture.

Top with another triangle, use a fork to crimp edges.

Place triangles on cookie sheet.

Brush with beaten egg and sprinkle turbinado sugar on top.

Bake at 375°F for 25 minutes until puffed and golden.
