In a sauce pan add the honey, brown sugar, balsamic vinegar, soy sauce, garlic, ginger, sriracha and season to taste with black pepper. Bring to a boil, then lower the temperature and simmer for 5 minutes, until the sugars have dissolved and the sauce is beginning to thicken. Remove from heat and allow to cool for a few minutes.
In the bowl of a slow cooker, add the skinned chicken drumsticks and pour the sauce over. Move the chicken around a bit with tongs to coat completely. Put the lid on and cook on high for 4 hours, flipping chicken a couple of times during the cooking process.
Remove chicken to a plate. Add the cornstarch to 1/4 cup cold water to make a slurry. Whisk into the chicken jus until thickened slighty. Return the chicken and coat well before serving.
Serve with steamed white rice, chopped cilantro, toasted sesame seeds, and your favorite veggies!
