These are super quick to make if you have ready-made pastry and can be whipped up in the morning for fresh, warm pastries. There are a number of substitutions you can use here—instead of the candied orange, use chopped dark chocolate or rum-soaked raisins. Or leave it out and swirl through a teaspoon of your favorite jam (I'd go for sour cherry) together with the ricotta on each pastry square.
These are best eaten warm or, at the minimum, on the same day they're made. —Emiko
sheet ready-made puff pastry (about 230 grams or 8 ounces of pastry)
(200 grams) ricotta
(65 grams) sugar
egg, separated (save the white for brushing the tops)
Grated zest of 1 lemon or orange
(30 grams) candied orange, finely chopped (see note for substitutions)
Powdered sugar, for dusting
Heat oven to 180°C/350°F.
Roll out the puff pastry on a baking sheet lined with parchment paper and with a sharp knife divide the dough into 12 even squares.
In a medium-sized bowl, stir together the ricotta, sugar, egg yolk (save the white for later), zest, rum (if using), and candied orange until smooth. I use a fork or a spoon.
Place about 1 heaped tablespoon of the ricotta mixture on the bottom corner of every square (not too close to the edges), then brush the rest of the surface of the pastry with the leftover egg white. Immediately fold over the opposite top corner to create triangles encasing the ricotta filling. Press the edges firmly down with fingers or with the tines of a fork.
Bake 15 minutes or until the pastries are puffed and golden. Dust with powdered sugar before serving.
