Beef Burgers with Cabernet Onion Jam

Serving Size  : 4    
 
1         tablespoon  butter
3         cups  very thinly sliced red onion (from 2 medium red onions)
2         tablespoons  coconut date sugar
3/4     teaspoon  salt — divided
2/3     cup  Cabernet Sauvignon wine
1         tablespoon  balsamic vinegar
2         pounds  lean ground beef
1/2     teaspoon  salt
1/4     teaspoon  black pepper

Heat the butter in a large skillet over medium heat. Add the onion, sugar, and 1/4 teaspoon of the salt and cook, stirring occasionally, until the onion is very soft, about 15 minutes. Add the wine and vinegar and cook until the liquid is nearly gone, 12 to 14 minutes longer (25 to 30 minutes total). Cover and set aside

Mix the beef, remaining 1/2 teaspoon salt, and pepper with a fork; form into four 3/4-inch-thick patties. Press your thumb in the center of each burger to form an indentation. Grill the patties 4 to 5 minutes, turn and grill another 4 minutes, and top with the cheese. Cook until the cheese is melted and the burger is cooked to desired degree of doneness (160° for medium).

Top burger with the onion jam.
