This recipe is actually called Warm Springs Vidalia Marmalade and its from the National Hot Dog and Sausage Council. But I don’t like the rosemary. It detracts from the overall recipe in my opinion and I’ve found you can use any onion you want. Vidalia is very sweet and nice but you can use any variety of sweet onion - Maui, Oso Sweet, Rio Sweet, etc. or even just regular yellow or white. But the sweet onions definitely give it a nice kick.

I have put this on burgers, hot dogs, bratwurst, sausages, etc. Anything I would want to have cooked onions on.

1 pound of onions, sliced very thin
1 teaspoon minced garlic
1 tablespoon balsamic vinegar
1 tablespoon brown sugar
1/4 teaspoon salt
1/4 teaspoon black pepper

Saute onions in olive oil over medium heat until lightly brown. Add garlic. Cook for 1 minute. Stir in remaining ingredients and reduce to low. Cook for 5 minutes until thick, stirring occasionally.
