Soak four wooden skewers in water for ten minutes.
For the kebabs, thread the orange pieces and brioche alternately onto the four wooden skewers and dust with the icing sugar.
Heat the butter in a frying pan over a medium to high heat and place the kebabs into the pan, fry for two minutes on each side.
For the sauce, melt all of the ingredients together in a small pan on a medium heat, stirring to combine. Pour the sauce into a serving bowl.
Place the kebabs onto a serving plate, dust with icing sugar and serve alongside the sauce.
