Preheat your oven to 355°F (180°C).
In a large mixing bowl, soak the breadcrumbs in milk until fully absorbed.
Stir in the melted butter, brown sugar, mixed spice, and beaten eggs into the breadcrumb mixture. Mix well.
Gently fold in the dried mixed fruit and orange rind.
Pour the mixture into a greased 9x13 inch baking dish.
Generously sprinkle the top with freshly grated nutmeg.
Bake in the preheated oven for 1 hour, or until set and golden brown on top.
Let the pudding cool slightly before serving. It can be enjoyed warm or cold.
