Peel and finely dice the onions. Wash the currants and remove from the stems. Boil up onions, currants, brown sugar and vinegar. Add vanilla pod, cloves and mustard seeds and boil down for about 30 minutes until thick.
Wash chicken legs, pat dry and season with salt and pepper. Put them on the fat pan of the oven. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 30 minutes.
About 5 minutes before the end of the cooking time, brush the legs with chilli sauce. Season chutney with salt and pepper. Take chicken legs out of the oven, let them cool down a little and wrap them with parchment paper at the thin end.
Tie up with kitchen string.
