Soak the raisins in a little water. Dice the onions and fry them in the melted butter until golden brown. Add the finely chopped garlic. Add the celery cut into pieces as thick as a thumb and the thinly sliced carrots and fry briefly. Now add the cream, the juice of the orange, the finely chopped ginger, the drained raisins and the mustard to the pan. Let everything simmer for about 10 minutes. The celery and carrots should still have bite. Season with the spices and herbs.
