Method

step 1

Melt the butter in a small saucepan over a medium heat, then stir in the flour and cook for 2-3 mins until light brown. Add the milk, a splash at a time, whisking well after each addition until smooth. Once all the milk has been added, bring to a simmer, whisking continuously. Cook for 3-4 mins more until thickened – this is your béchamel sauce. Remove from the heat and whisk in the mustard and 40g of the cheese. Leave to cool.
step 2

Unroll the puff pastry, leaving it on its sheet of baking parchment. Cut into 12 x 8cm squares. Rotate each square 90 degrees so it forms a diamond shape, then spoon 2 tsp of the béchamel down the middle. Top with some ham and a little of the remaining cheese, then fold over one of the edges. Brush with the beaten egg or milk, then fold over the opposite edge. Brush all over with more egg, and grind over some black pepper. Repeat until all the ingredients have been used.
step 3

Heat the air fryer to 180C and cook in batches for 10-12 mins until puffed up, golden and bubbling. Serve warm. Once cool, will keep chilled for up to two days. Reheat in the air fryer at 120C.
