!For the Sauce:
Combine all the ingredients except cornstarch and cold water in a small saucepan. Bring to a boil over medium heat. In a small bowl stir together cold water and cornstarch with a fork, breaking up any clumps. Pour cornstarch mixture into boiling sauce and whisk until thickened. Keep sauce warm over low heat while you make the chicken.
!For the Chicken:
Pour about 1 inch of oil into the bottom of a dutch oven over medium-high heat.
Add beaten eggs to a large bowl and add chicken pieces. Coat well.
In another bowl, combine flour, cornstarch, and seasoning salt. Working in batches, take chicken from the egg mixture and coat in the flour mixture. Place chicken pieces into the hot oil, being careful not to overcrowd the pan. Fry the chicken until golden and crispy on the both sides and cooked through. Using a slotted spoon, remove fried chicken to paper towels to drain. Repeat with remaining batches of chicken until all the chicken is fried and drained.
Pour the hot orange sauce over the fried chicken and stir to coat. Top with sliced green onions and serve promptly over steamed rice.
