DESSERT IN A PINCH: PALMIERS7:55 AM
1/8 teaspoon kosher salt
2 sheets puff pastry, defrosted (recommended: Pepperidge Farm)
Preheat the oven to 450 degrees F.
Fold the sides of the square towards the center so they go halfway to the middle. Fold them again so the two folds meet exactly at the middle of the dough. Then fold 1 half over the other half as though closing a book. You will have 6 layers. Slice the dough into 3/8-inch slices and place the slices, cut side up, on baking sheets lined with parchment paper. Here's a visual for this step in case you need it.
Place the second sheet of pastry on the sugared board, sprinkle with the remaining 1/2 cup of sugar mixture, and continue as above. (There will be quite a bit of sugar left over on the board.) Slice and arrange on baking sheets lined with parchment.
Bake the cookies for 6 minutes until caramelized and brown on the bottom, then turn with a spatula and bake another 3 to 5 minutes, until caramelized on the other side. Transfer to a baking rack to cool.
