Hey Mike!
I really like this one! the conjunction of flavors: roundness of sesame oil, sweetness and spiciness: a nice blend for a joyful culinary moment!
Again: thank you so much! - Jérémie
Whisk together ketchup, soy sauce, brown sugar, pineapple juice, vinegar, sesame oil, hot sauce, ginger and garlic. Reserve some marinade for basting. Marinate the chicken either in the bowl or in a large sealable bag in the refrigerator.
When you're ready to cook, heat up your grill. Discard the used marinade, then grill the chicken until done! Baste the chicken during grilling with the reserved marinade. Chicken is done when it reaches an internal temperature of 165 degrees F (74C).
