1. Put all the pastry ingredients into a bowl and mix quickly by hand into a
dough. Don’t knead too much.
2. Put the dough to a cold place to harden.
3. Roll out on a floured board, folding a few times to make a puff pastry, and
finally make a 1/2 cm thick sheet.
4. Cut the sheet into 7 x 7 cm squares. Split the corners of each square.
5. Place a bit of prune puree or plum jam in the middle of each square. Fold
over every other split end onto the center, to form a windmill-like pastry.
6. Brush with beaten egg and bake at 450° F until light brown. To make round
pastries, cut into circles, fill, and fold in half. Bake as above.
