8 boneless skinless chicken breasts (cut into bite-sized pieces)
Instructions
In a medium saucepan combine ketchup, soy sauce, vinegar, brown sugar, and white sugar. In a cup whisk together the pineapple juice or water with the 3 tablespoons of cornstarch until smooth. Whisk into the ketchup mixture in the saucepan.
Bring to a boil while stirring constantly over medium-high heat until bubbly. Remove from heat and allow to sit until at room temperature until cooled to serve.
To prepare the chicken: In a large bowl combine flour, cornstarch, baking powder, baking soda, and garlic powder.
Add in water and sesame oil. Whisk until smooth. Add in the chicken pieces and mix well to coat the chicken with the batter.
Heat oil in a deep-fryer to 375 degrees F. Fry the battered chicken pieces in batches until golden brown and fully cooked (the internal temperature has reached 165 degrees F.), about 5-6 minutes. Drain on a plate lined with paper towels.
Serve immediately with sweet and sour sauce. You can also toss the chicken with the sauce if you would prefer.
