Preheat oven to fan forced 180ºC and blind bake for 20 minutes. Remove beans before filling

Pour into pastry base and tap on bench to settle filling. Top with blueberries and return to oven for 5 minutes.
Cool before serving dusted with reserved lemon and cardamom sugar and of course, the obligatory dollop of whipped cream…oh well, I now balanced out the burnt calories of this morning. A happy excuse for dessert tonight at least!
