Also known as elephant ears, shoe-soles, palm trees or palm leaves, palmiers are delicious pastries that can be served for breakfast or dessert. All you need is puff pastry, sugar, parchment paper, a rolling pin and an oven. When these are baked, the sugar caramelizes beautifully yielding a buttery and flaky "cookie". They look fancy and you don't have to tell your guests how easy they are to make
Thaw the puff pastry sheet, according to package directions. Spread an even layer of sugar onto a pastry board. Place the thawed pastry sheet on top of the sugar.
Sprinkle a layer of sugar on top of the pastry sheet. Gently roll the pastry sheet, pressing with a medium firmness to push the sugar into the dough.
Spread a very thin layer of seedless raspberry jam (if using) that has been microwaved about 15 seconds for a thinner consistency, onto the puff pastry--leaving about a 2" border all the way around. Turn the dough with the short side facing you. Fold the end closest to you about 1 1/2" inward. Do the same from the other side.
With a rolling pin, press the dough together. Be careful not to press too hard, or the jam will ooze out.
Again, fold another 1 1/2" inward on each side. Now, fold one side on top of the other, add additional sugar and press again with a rolling pin.
Using a sharp knife, cut about 3/8" slices and place about 1 1/2" apart on parchment paper. Freeze for 15 minutes, or refrigerate for 30 minutes.
Don't skip this step!
Preheat the oven to 375˚F.
Bake for 15 to 20 minutes, depending on your oven, until golden brown.
