I used up the remaining buttermilk I had by marinating boneless, skinless chicken breasts (butterflied) for the grill. The kicker was the OB's Irie Pepper Sauce I added to the mix. This is, so far, my hands down favorite way to use OB's. I saved one breast for the skillet and got great results there, too. This will be the method I use on fried chicken next time.
4 boneless, skinless breasts - butterflied
2 cups buttermilk
1 tbsp salt
1 tbsp brown sugar
1 tbsp OB's Pepper Sauce
1/2 tbsp Sriracha
Mix marinade ingredients until salt and sugar dissolve. Add chicken. I soaked for 6 hours. Turn pieces every hour. I'd probably double the salt and sugar if only soaking for an hour. I went lighter on the OB's than most of you would but it still makes itself nicely known. Not sure if the Sriracha was necessary but it was already on the counter so I used it.
