To assemble the phyllo pie, using a pastry brush, butter an 8 inch springform pan with removable bottom.
Place phyllo sheets between a damp tea towel, this will ensure it does not dry out. Brush one phyllo sheet with melted butter and place in spring form pan ensuring phyllo sheet is over lapping over sides of pan. Repeat with an additional 7 sheets of phyllo, alternating in the pan. Add custard inside phyllo and spread out evenly. Tuck in the overlapping phyllo around the inside edge of the pan, around the custard. Place in oven and bake for 45-50 minutes until phyllo is golden in colour and custard has set. Remove from oven, allow to cool for 10 minutes prior to removing from pan.
While pie is cooling, add strawberries in a medium bowl and toss with vanilla sugar, strawberry jam and fresh mint.
Place pie on platter and remove from pan. Poke about a dozen holes half way through the custard with a skewer, this will help the delicious fruit juice moisten the custard. Top with strawberry topping and enjoy.
