Chocolate jaffa pudding

Grease a 2-litre baking dish with butter and preheat oven to 160°C fan/gas 4. Pop the kettle on. Add the flour, caster sugar, 50g cocoa, baking powder, orange zest and a pinch of salt into a large mixing bowl. Mix together the orange juice, pulp, eggs melted butter and milk then pour onto the dry ingredients mixing together until smooth. Stir in the chocolate chunks and tip everything into the baking dish,

Mix 300ml boiling water from the kettle with the sugar and cocoa to make the sauce, and then pour this all over the batter. It looks quite odd at this stage but it will all turn out!  Bake in the oven for 30 minutes until the surface looks firm, risen and crisp. Serve straightaway with vanilla ice cream or single cream.
