Directions
In a medium bowl, whisk together the balsamic vinegar, soy sauce, Yacon syrup, olive oil, chili sauce, and minced garlic.
Season with salt and pepper.
Pour half of the marinade into a large resealable bag with the chicken thighs.
Reserve the other half of the marinade. Seal the bag, shake well to coat, and refrigerate for at least 1 hour.
While the chicken marinates, preheat your oven to 425°F (220°C).
Pour the reserved, unused marinade into a small saucepan.
Bring to a boil over medium heat, then reduce heat and simmer for 5-7 minutes until it thickens into a glaze.
Remove from heat and set aside.
Remove the chicken from the bag, discarding the used marinade.
Arrange the thighs in a single layer in a 9x13-inch baking dish.
Brush the cooked glaze generously over the chicken thighs.
Bake for 30-35 minutes, or until the chicken is cooked through and the internal temperature reaches 165°F (74°C).
Garnish with sesame seeds and serve hot.
