Put flour in a bowl, add butter and rub together until fully incorporated. Add turmeric powder and baking powder and a pinch of salt. Add water as required and mix together, knead until a smooth dough is formed. Set aside!

Put water in a pot and boil the carrots and potatoes until half cooked, drain to remove excess water. Put again in a pot, add the fish, pepper, onions, some seasoning cubes and salt to taste, add little curry powder, stir, cover and allow to steam. Set aside.

Roll out a portion of the dough, cut into squares, rub an egg or flour mixture on the surface, add the filling, and roll to the edge. Lay on a baking tray greased with butter. Complete the process to finish up all the dough. Poke with a fork to aid baking, rub raw egg on the surface for that moist and shiny look. Bake until a toothpick inserted in the middle comes out clean.
