combine apple cider, kosher salt, garlic, thyme and rosemary in a glass bowl. Add pork chops and mix well with marinade. Marinate for 30 minutes to one hour, refrigerated.
Remove chops from the marinade and pat dry.
Broil or cook pork chops on an open grill for approximately 10 minutes, turning as needed. Serve with red onion marmalade.
RED ONION MARMALADE:
(marmalade may be made up to 2 days ahead).
3 tablespoons extra virgin olive oil
10 cups red onions, thinly sliced
1 tablespoon brown sugar
to taste salt and white pepper
3/4 cup red wine vinegar
1 1/4 cups red wine
Heat olive oil in a large heavy bottomed saucepan and add the onions. Cook over medium heat until they begin to soften, about 10 minutes, then add the brown sugar and stir to coat. Season with salt and pepper.
Continue cooking over medium heat, stirring frequently, or bake in a 350 degree oven until the onions are golden soft and brown.
Add the vinegar and cook until it has completely evaporated, then add the red wine stirring the onions frequently to prevent sticking and burning. When the red wine has evaporated, taste and adjust the seasoning. Remove from heat and keep warm
