1c balsamic vinegar

1/2c worcestershire sauce

1/4c lemon juice

1 1/2c brown sugar (I use maple sugar)

4 tsp dried rosemary

4 Tbsp Dijon mustard

1 Tbsp salt

2 tsp freshly ground black pepper

4 tsp garlic powder

up to 7 lbs chicken breasts (maybe 10-12)

I make this in bulk and only use it as needed. My recipe fills an entire 1 qt container.
