How To Make Onion Jam

Besides garlic, I love onion, especially when they are caramelized. It can go well on almost anything. You can place the onion jam on some toasts, grilled cheese sandwiches, burgers and even pizzas. Yes, I saw Frank Pinello uses it for his white pizzas. Maybe in the future, I will be paying homage to his pizza. Anyway, I am using a combination of yellow and red onions. I like the contrast. The key is to be patience as the heat has to be low, or you will burn your onions. It will take between 40 to 50 mins. So, be patient. It will pay off.
