I have made tricolour tart for this celebration. For this you may use home-made tart shell or a store-bought tart.
Remove the pre baked tart shell from the packaging and place on the counter.
Clean and wash grapes and physalis. Keep aside.
Preparing Cream: In a mixing bowl, take out mascarpone cheese. Add in vanilla essence and sugar.
Spoon the cream mixture all out into the both pastry base, smoothing with a spatula or a palette knife.
Decoration: In the small tart make 24 lines using blue gel colour. Place the small tart in the center of big tart.
Refrigerate for at least 1 hour before cutting and serving.
