Actually, Barbara is right (women usually are) you are actually making an onion brulee just like the term used in desserts. It refers to surface caramelization of food. Cut the onion in half and melt a small amount of butter in a skillet over medium heat. Add the onion, cut side down, and let it cook until the surface caramelizes 8-12 minutes.
