Add the dried orange peel
Set aside
Combine 2t sesame oil, 2t minced garlic, 2t fresh ginger, and 2t minced scallions in a large skillet, and place over medium heat.
Cook, stirring, until the vegetables are aromatic and soft but not browned (about 3 minutes)
Stir the sauce mixture and add to the skillet making sure to scrape anything stuck to the bottom or sides of the skillet
Cook, stirring until the sauce boils and thickens (about 1 minute)
Transfer the sauce to a bowl to stop the cooking, take the skillet off the heat, but do not clean the skillet
For the finish
Heat 1-1/2qts of peanut or vegetable oil in a large wok or Dutch oven to 350F and adjust the heat to maintain this temperature
Working one piece at a time, add the chicken to the dry coat mixture, tossing between each addition to coat the chicken
When all of the chicken has been added to the dry coat, toss and press the dry coat into the chicken so that it adheres and making sure that all of the chicken is coated thoroughly.
Lift the chicken a piece at a time, shake off the excess coating, and carefully lower it into the hot oil
Once all of the chicken has been added, cook, agitating with a long chopstick or spider until the chicken is cooked through and very crispy (about 4 minutes)
It is VERY IMPORTANT to maintain an oil temperature at 350F. You may need to cook your chicken in smaller batches to achieve this.
Transfer the chicken to a paper towel and drain
Add the chicken to the empty skillet, and return the sauce to the skillet
Toss or stir the chicken until folding it with a spatula until all pieces are thoroughly coated with sauce
Serve immediately with white rice
