Food Special Caramelized Onions, Made Simple An easy way to go for the gold.
All onions become sweeter with caramelization.
We often use yellow onions to test our recipes, although white and red varieties work well, too. 1 pound of onions yields about 3 cups vertically sliced onion. 3 cups slivered onion yield about 1 cup caramelized onion. Stir occasionally during the first 5 minutes of caramelization, then more frequently during the last 10 or so minutes. It's important to keep the onions moving.
