  2. Add the butter and continue to cook, stiriring occasionally, for another 15 minutes until onions are caramelized and sweet. Remove to a plate.
  3. Mix together the seasoning ingredients, (salt, pepper, onion powder, garlic powder and sugar.)
  4. Shape burger into 4 patties and season with seasoning mixture. Wipe out skillet, grease, and heat over medium heat. Place burgers in skillet and cook for a few minutes until half-way cooked, turn over and cook to your desired doneness.
  5. When burgers are done, remove the pan from the heat, dash each burger with worcestershire, place a slice of fontina on top of each, and cover the skillet with a lid.
  6. Meanwhile, turn oven broiler on high. On a baking sheet place buns cut side up and place a slice of gruyere on each piece. Place under broiler until cheese bubbles up and browns.
