Place berries in a small bowl, sprinkle with sugar, and toss gently with liqueur or juice. Let soak at room temperature at least one hour. Preheat oven to 400°F. Cut pastry sheet into nine 3x3-inch squares. Bake squares on parchment-lined cookie sheet until golden brown, 15 to 20 minutes. Cool and separate each pastry square to create a bottom and lid for each puff. Meanwhile, in a small bowl, combine cream cheese and honey; set aside. Whip cream until soft peaks form; fold cream cheese mixture into whipped cream. To assemble dessert, place bottom of each pastry on individual plates, top with a dollop of cream cheese mixture, top with puff pastry lid, and spoon over berries and liqueur. Dust with powdered sugar, if desired; serve immediately. Makes 9 puffs.
