Preheat oven to 400 degrees.

Whisk egg and water together in a small bowl and set aside.  Place puff pastry on a lightly floured work surface.  Use a rolling pin to lightly roll out pastry into about a 9 x 12 area (doesn't have to be exact!)  Cut into 12 even squares. Cut brie into 1-inch squares (more or less as desired.)  For sweet and spicy version, spoon a little pepper jelly over the top of each (1-2 teaspoons).   For Fig version, combine 2 parts fig jelly with 1 part balsamic and whisk until smooth.  Spoon over cheese. 

When all squares are filled, grab the corners of the pastry and pull them together, using your fingers to pinch dough and seal closed. 

Place each one a couple inches apart on a parchment-lined baking sheet.  Use a brush to brush egg wash over each pastry.  Bake until puffed and golden brown, about 20 minutes. Sprinkle green onions over sweet and spicy if desired. 

May be served warm or at room temperature.
