Melt the butter in a medium pan and add the sliced red onions and brown sugar, stir often over a medium heat for about 10-15 minutes until the onions are soft and slightly caramelized.
Add the Red Wine and Red wine vinegar and get all the sediments from around the base and side of the pan to deglaze. This is best done using a wooden spoon.
