Add the FAMA butter 82%, the FAMA Soft G+ margarine and the icing sugar to the mixer bowl and mix with the flat beater until the mixture becomes fluffy and airy. Then, slowly add the eggs and the rest of the ingredients, which you have sifted beforehand. Spread the dough on an 30X40 oven pan and fill it with the Thermostable Pastry Filling Frutopia with Apple in Pieces. Decorate the top of the pie with strips made from the dough; first place half of the strips on top of the filling and then place the rest of the strips crosswise on top of the first set. Bake in a pre-heated rack oven at 220°C  (high) and at 190°C (low) for about 45 minutes.
