Step 1

Preheat oven to 375°. Combine the first 12 ingredients. Refrigerate, covered, at least 1 hour.

Step 2

Meanwhile, on a lightly floured surface, unfold puff pastry. Roll each pastry into a 10-in. square; cut each into twenty-five 2-in. squares. Using a round 1-1/2-in. cookie cutter, cut out the centers of half the puff pastry squares. Whisk egg and water; brush over pastry. Place cutout squares on top of solid squares; transfer to parchment-lined baking sheets.

Step 3

Bake until golden brown, about 18 minutes. Cool to room temperature. Once cool, spoon 1 heaping tablespoon of crab salad into center of each cooked pastry. If desired, top with minced parsley and seasoning. Serve immediately.
