Prepare the crust: in a medium bowl, combine the flour, salt, and baking powder
Add the butter and mix with your fingers until the mixture resembles coarse crumbs
Gradually add the ice-cold water, stirring with a fork until the dough comes together
Form the dough into a ball and knead it on a floured surface until it forms a disk about 15cm in diameter
Wrap in plastic wrap and refrigerate for at least 15 minutes. Reserve
Prepare the filling: in a medium saucepan, combine all the ingredients and cook over medium heat, stirring constantly with a wooden spoon, until the mixture thickens (about 10 minutes)
Remove from heat and let cool to room temperature (about 30 minutes)
Preheat the oven to 180°C (medium)
Roll out the reserved dough on a floured surface to a thickness of about 3mm
Place the dough into a 35cm diameter tart pan with a removable bottom, turning the edges up to form a crust
Spread the filling over the dough, leaving a 5cm border around the edges
Fold the crust over the filling, but keep the center open
Brush the crust with the lightly beaten egg
Bake in the preheated oven until golden brown (about 30 minutes)
