                    Melt the butter in a large skillet over medium heat. Add the onions, salt, pepper, and cayenne. Cook, stirring occasionally, until the onions are translucent (about 10 minutes). Reduce the heat to medium-low, and continue to cook until the onions are golden (about 10 minutes).

                    Add 2 tbsp of water to the skillet, and cook, scraping up any browned bits, until the water has evaporated (about 5 minutes).  Add the remaining water and cook until the onions are caramelized and the water has again evaporated (about 5 more minutes).
