Lemon Blackberry Danish Ricotta Puff Pastry Pinwheels Step-by-step instructions

Before you start

Before starting, ensure the puff pastry is thawed but still cold. If using frozen pastry, transfer it to the refrigerator the night before. Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.

Grate the lemon white chocolate using a box grater and set it aside. Measure out the ricotta, lemon curd, and blackberries. Have the vanilla icing ready in a small bowl or piping bag. Work in a cool kitchen to keep the pastry from becoming too soft.

Instructions

Prepare and Assemble

1. 1Prepare the Pastry and Chocolate
   Heat the oven to 400°F (200°C). Line a baking sheet with parchment paper. Unfold the thawed puff pastry on a lightly floured surface. Cut the pastry into 4 equal squares, then cut each square diagonally to make 8 triangles. Score the corners of each triangle lightly with a knife, about 1/2 inch from the edge, to help them puff evenly. Grate the lemon white chocolate on the large holes of a box grater into a bowl and set aside.
   Look for The pastry squares are evenly cut and the corners are scored without cutting through.
   Tip Keep the pastry cold while working; if it warms up, chill it for 10 minutes before baking.
2. 2Mix the Ricotta Filling
   In a small bowl, stir the ricotta cheese until smooth and creamy. If the ricotta is very wet, drain it in a fine-mesh strainer for 5 minutes before using. Spoon a generous tablespoon of the ricotta into the center of each pastry triangle. Top each with a teaspoon of lemon curd, spreading it slightly over the ricotta.
   Look for The ricotta is thick and holds its shape when spooned.
   Tip For a smoother texture, press the ricotta through a sieve before using.
3. 3Assemble the Pinwheels
   Fold the three corners of each pastry triangle toward the center, overlapping them slightly to create a pinwheel shape. Press the center gently to seal the filling inside. Place the pinwheels on the prepared baking sheet, leaving at least 2 inches between them. Press a few blackberries into the top of each pinwheel, slightly sinking them into the ricotta mixture.
   Look for The pinwheels are neat and the blackberries stay in place when pressed.
   Tip Work quickly to keep the pastry cold; if it softens, chill the assembled pinwheels for 10 minutes before baking.

At the end of this phase, the pastry squares are cut and scored, the ricotta and lemon curd are mixed and ready, and the pinwheels are assembled on the baking sheet. The pastry should still be cold and firm to the touch. The blackberries are gently pressed into the filling, and the pinwheels look neat and uniform. If the pastry has softened, chill it for 10 minutes before baking to ensure a flaky result.

Bake and Finish

4. 4Bake the Pinwheels
   Bake the pinwheels for 18 to 20 minutes, until the pastry is golden brown and puffed and the filling is bubbling. Rotate the baking sheet halfway through for even browning. The blackberries will soften and release some juice. Remove from the oven and let cool on the baking sheet for 5 minutes, then transfer to a wire rack.
   Look for The pastry is deeply golden and flaky, and the filling is hot and bubbly.
   Tip If the edges brown too quickly, tent loosely with foil for the last 5 minutes.
5. 5Drizzle with Icing
   While the pinwheels are still warm, drizzle the vanilla icing over the tops using a spoon or a piping bag. Let the icing set for about 2 minutes. Then sprinkle the grated lemon white chocolate generously over the icing, covering the tops and the exposed pastry edges.
   Look for The icing is drizzled in a zigzag pattern and the chocolate curls stick to the icing.
   Tip For a cleaner look, drizzle the icing after the pinwheels have cooled slightly but are still warm to the touch.

After baking, the pinwheels are golden brown and puffed, with a fragrant aroma of butter and lemon. The filling is bubbly and the blackberries have softened. The icing drizzles smoothly over the warm pastry, and the grated chocolate curls stick to the icing. The pinwheels look glossy and inviting, with a beautiful contrast of colors. Let them cool for a few minutes before serving to allow the icing to set.

Serve and Enjoy

6. 6Serve Warm
   Serve the pinwheels warm, while the pastry is crisp and the filling is creamy. Use a spatula to lift each pinwheel from the baking sheet. The contrast of the flaky pastry, tangy lemon curd, sweet ricotta, juicy blackberries, and the vanilla-chocolate drizzle is best enjoyed right away.
   Look for The pinwheels are golden, flaky, and topped with glossy icing and chocolate curls.
   Tip If serving later, warm them in a 350°F (175°C) oven for 5 minutes to refresh the crispness.

The pinwheels are served warm, with the pastry crisp and flaky. The filling is creamy and tangy, and the blackberries are juicy. The vanilla icing is set but still slightly soft, and the chocolate curls add a delicate crunch.

Each bite offers a mix of textures and flavors, from the buttery pastry to the smooth ricotta and the bright lemon curd. They are best enjoyed fresh, but can be reheated briefly if needed.

Common mistakes

One common mistake is overworking the puff pastry, which can make it tough. Handle it as little as possible and keep it cold. Another mistake is adding too much filling, which can cause the pastry to become soggy or burst open during baking.

Use a generous tablespoon of ricotta and a teaspoon of lemon curd per pinwheel. Also, avoid pressing the blackberries too deep into the filling, as they can release too much juice. Finally, do not skip scoring the corners; this helps the pastry puff evenly and creates the signature pinwheel shape.

How to tell it’s done

The pinwheels are done when the pastry is puffed and golden brown, with a deep golden color on the edges and a slightly darker bottom. The filling should be bubbling around the edges, and the blackberries should be soft and slightly caramelized.

A toothpick inserted into the center of a pinwheel should come out clean, with no raw dough. The internal temperature of the pastry should be at least 200°F (93°C) to ensure it is fully baked. Let them cool for a few minutes before drizzling with icing.
