Preheat frying oil to 325 degrees F.
Combine salt, pepper, cornstarch, flour and baking soda in a medium bowl. Season chicken with flour mixture, making sure to thoroughly coat all sides. Let sit for 10 minutes.
Fry chicken drumsticks until light brown in color about 10 minutes. Remove from heat and drain on paper towels. Return chicken to the fryer and fry once more for another 10 minutes or until crispy and golden brown.
Meanwhile, prepare the sauce. Heat the sesame oil in a medium sauce pan over medium-low heat. Add the garlic and saute until aromatic, about 30 seconds. Add the remaining ingredients (rice syrup - rice vinegar) and bring to a simmer, stirring frequently. Remove from heat. Toss the chicken in the sauce and sprinkle sesame seeds on top. Serve immediately.
