Cut the pastry into graduated squares: large (8.9–10 cm), medium (7.6 cm), small (5.1 cm), and very small (2.5–3.8 cm), aiming for 4 to 5 squares per stack.

For the bottom 2 to 3 layers, build layers by placing: puff pastry square, ham slice, cheese slice, then another puff pastry square to create a melty base. Upper layers remain plain puff pastry squares.
