1. Mash the sweet potato with the curry paste and coconut milk to taste:go for a slightly intense flavour,as the pastry seems to dampen the spices. Stir in the pork,onion,capsicum and eggplant then add salt to taste. Chill this while you line the tins.
2. Butter the inside of six pie tins,about 10 to 12 centimetres in diameter,with melted butter. Line the tins with discs of shortcrust pastry,letting about one centimetre of pastry hang over the edge. Then divide the mixture between the tins,heaping it up if you need to.
3. Cut six discs of puff pastry large enough to cover the tops of the tins,and brush each lightly with beaten egg.
4. Place the discs egg-side down onto the pastry,so they stick,and crimp the edges together. Beat a teaspoon of curry paste with the remaining beaten egg wash and brush this over the top,then sprinkle with sesame seeds.
5. Chill the pies for an hour. This helps seal the edges.
6. Bake at 180C for about 30-40 minutes until deep golden brown and piping hot inside.
