Instructions
Use a spatula to fold the lemon curd and custard together in a bowl until just combined.
Cut a sheet of pastry in half and mark out 6 rectangles on one half.
Place 1 tablespoonful of curd mixture into the center of each rectangle.
Place the remaining pastry half over the top and press between custard and along edges to seal.
Cut into 6 rectangles and repeat with remaining pastry and filling to make 12 bars.
Place 3-4 rectangles inside the air fryer basket.
Cook at 180C for 5 minutes, then turn bars over and cook for a further 3 minutes until puffed and golden.
Transfer to a wire rack and repeat with remaining rectangles.
Dust with icing sugar and sprinkle with lemon rind to serve.
Pro Tips
Fold the curd and custard together until just combined to maintain the desired consistency.
Ensure the pastry edges are firmly sealed to prevent the filling from leaking during cooking.
Work in batches to avoid overcrowding the air fryer basket for even browning.
Cool the bars on a wire rack to keep the pastry crispy.
