Palmier is a delicate pastry in the shape of a leaf or a butterfly made of puff pastry and sugar. The word is French meaning palm leaf but they are known under other names as well: pig's ears, elephant ears, prussiens or Cœurs de France. And now to the recipe:
ready-made puff pastry
Pre-heat the oven to 200° C . Combine the sugar and the spices. Roll out the puff pastry to 4mm thick. Sprinkle about half the sugar mixture onto the pastry and gently roll the rolling pin over the surface to press the sugar in. Turn the pastry over and repeat on the other side with more of the sugar. Now fold the sides in so they meet neatly in the middle. Flatten and sprinkle with a bit more sugar in between folding. Alternatively you could roll the sides up as well.
Cut the folded pastry into 1cm thick slices and place to chill in the fridge for about 15 min. Then take out and arrange on a baking tray lined with grease proof paper leaving enough space between them as they will puff up. Bake for 15 min.
