Grilled Mongolian Pork Chops
Combine hoisin sauce, garlic, soy sauce, ginger, 1 tablespoon red wine vinegar, rice vinegar, sherry vinegar, sesame oil, 2 teaspoons sugar, hot sauce, white pepper, and black pepper in a large bowl. Whisk thoroughly and set aside.
Place pork chops in a resealable freezer bag; pour slightly more than 1/2 the marinade into freezer bag over pork chops. Seal bag and refrigerate for 6 to 8 hours. Reserve remaining marinade.
Combine 1/4 cup red wine vinegar, 3 tablespoons sugar, 2 tablespoons hot mustard powder, and egg yolk in a small saucepan over medium-low heat. Whisk until slightly thickened, about 5 minutes; remove from heat.
Stir in creme fraiche, Dijon mustard, turmeric, and cayenne pepper. Refrigerate until needed.
Remove pork chops from marinade and pat dry using paper towel.
