How to Make It
Heat oven to 400° F. Line 2 baking sheets with parchment. Unfold the pastry and, using a 2-inch cookie cutter, cut out rounds. Place them on the prepared baking sheets.
In a medium bowl, mix together the cream cheese, mayonnaise, chives, lemon juice, ½ teaspoon salt, and ¼ teaspoon pepper. Fold in the crabmeat.
Dividing evenly, spoon the crab mixture onto the pastry rounds (about 2 teaspoons each). Bake, rotating the baking sheets halfway through, until the puffs are golden and crisp, 20 to 25 minutes. Sprinkle with additional chives and serve.
