½ vanilla bean, split lengthwise, seeds scraped and reserved*
½ (17.3-ounce) package frozen puff pastry, thawed
Instructions
In the work bowl of a food processor, combine pecans, sugar, salt, cardamom, and vanilla bean seeds. Process until mixture is uniformly incorporated and is the texture of fine sand.
Pour about half of sugar mixture onto work surface. Place puff pastry on top, and sprinkle with additional sugar mixture. Begin rolling pastry, working quickly, incorporating more sugar (as you would when flouring your board while rolling piecrust or cookies). Roll up dough, jelly-roll style, beginning with each long end and meeting in the middle. Place rolled dough in the freezer until firm, 10 to 15 minutes.
Line a baking sheet with parchment paper, and spritz with water.
Cut dough log into ¼-inch thick slices, and place palmiers about 2 inches apart on prepared pan. (See Note.) Freeze sliced cookies for 1 hour.
Preheat oven to 425°F. Bake palmiers for 8 to 10 minutes, turning with a spatula halfway through baking. Let cool completely on a wire rack.
Notes
You will need to work in batches. It is OK to slice the entire log at once and place slices on a parchment paper-lined sheet pan in the freezer. Bake straight from the freezer about 12 at a time.
