Get your oven ready by setting it to 200°C (400°F) or follow the directions on your pastry package. On a surface sprinkled with a bit of flour, open the puff pastry. Grab a knife or a cookie cutter and make either rectangles or hearts out of the pastry. Put them spaced out on a baking tray with parchment paper.

Mix up the egg with a tiny splash of water, then lightly brush the tops of your pastry pieces so they brown nicely in the oven.

Pop them into the oven for about 15–20 minutes. Take them out when they look puffed and golden. Let them sit and cool down completely on a wire rack or leave them on the pan.

Take a cold bowl and use an electric mixer to whip the chilled cream slowly until it thickens. Sprinkle in enough icing sugar to sweeten the cream as you go. Mix in the cocoa syrup, then keep beating until stiff peaks form. Stop before it turns grainy.

If you made hearts, carefully cut them into two layers. Spread strawberry jam on the bottom piece and spoon or pipe whipped cream over it. Add a few slices of strawberries, then gently set the top pastry back on. For rectangles, just layer jam, cream, and berries on top.

Take a sieve and coat the top of the cream puffs lightly with powdered sugar. Drizzle melted chocolate over each one. Serve right away or keep them in the fridge until eating time.
