Loosely place one round of puff pastry in a tart or pie pan. Place the wheel of Brie on top, then spread the jam on top of this and a bit on the pastry. Sprinkle with the almonds and place the other pastry round on top. Roll the edges of the pastry rounds together to seal them.
Bake at 375°F or 190°C for 25 minutes. Remove from the oven and allow the pastry to cool for just a bit before slicing and serving. This should be served and eaten straight away, although you can warm leftovers in the microwave (watch out, it reheats very quickly).
