I just love custard slice! and this Lemon Custard Slice recipe takes it to the next level whilst still being easy to make. I generally have puff pastry and homemade lemon curd in my freezer and limoncello in the drinks cupboard. Homemade mascarpone is much cheaper than buying it but of course you can pick up a pack from the supermarket.
2 sheets pre-rolled frozen puff pastry, defrosted
1 cup lemon curd
250 gram tub mascarpone
2 tblsp citrus-based liqueur (Limoncello, Grand Marnier)
1 ½ cups icing sugar
3-4 tblsp lemon juice
2 tsp grated lemon rind to garnish
Place the defrosted sheets puff pastry on a baking paper lined tray and cut in half. Prick each piece well with a fork.
Bake at 230°C for 8-10 minutes or until the sheets are well risen, golden and well cooked. Remove from the heat and, when cold, crush lightly.
Mix together the lemon curd, mascarpone and liqueur. Spread this mixture on top of two bases of puff pastry. Top each with the remaining cooked sheet of puff pastry.
Sift the icing sugar into a bowl and stir in sufficient lemon juice to make a thick icing of spreadable consistency.
Spread over the icing and garnish with lemon rind (and edible flowers if you wish). Cut into slices to serve.
