10 lbs Onions
1/2 tsp Sea Salt
2 TBS Balsamic Vinegar
Thinly slice the onions. Place onions in large pot, Dutch Oven type container on medium heat covered, until you hear them boiling, then turn heat down to low. Allow to braise in pot for 45 minutes, to an hour. They will be reduced by about 2/3d's, now uncover, and allow to simmer until the liquid is reduced, but there is still a little moisture. This can take hours, depending upon your humidity. Now can the finished product.
This process makes for a very sweet relish, all natural. Love it in steak sandwiches with roasted red peppers, and mayonnaise on a baguette, to die for. Use your imagination great with meat dishes, served cold in a salad, etc.
