1Cut boneless and skin on chicken leg into 1-inch size pieces. You can use chicken breast if you wish to.
2Marinate the chicken with 1 tsp of grated garlic, 1.5 tsp of soy sauce, 1/2 tsp of salt, some black pepper to taste, 3/8 tsp of baking soda, 1 egg white, and 1/2 tbsp of starch. Mix everything until well combined. Cover it and let it sit for 40 minutes.
3Add half of the starch into a big container. Spread it out. Add in the chicken. Cover the meat with the other half of the starch. Put on the lid and shake for a few minutes or until the chicken is coated nicely
4Heat up the oil to 380 F. Add the chicken piece by piece. In less than 2 minutes, you can feel that the surface is getting crispy and the color is slightly yellow. Take them out. Then we gonna do the second batch. Before that, you might want to fish out all those small little bits.
5Keep the temperature at 380 F, and fry the second batch of the chicken. Once you are done, let all the chicken rest for about 15 minutes and we gonna double fry the chicken.
6In a large bowl, add in 3 tbsp of brown sugar, 2 tbsp of liquid honey, 2.5 tbsp of soy sauce, 2.5 tbsp of ketchup, 3 tbsp of water, 1 tbsp of vinegar. Mix them until well combined.
7Put your wok on the stove and pour all the sauce in. Keep stirring the sauce on medium heat. Bring it to a boil and pour in some potato starch water to thicken the sauce. Keep stirring until it reaches a thin syrup texture.
8Introduce the chicken back into the wok, along with a drizzle of sesame oil and 1.5 tbsp of toasted sesame seeds. Toss everything until the chicken is coated nicely. Take them out.
9Garnish it with some diced scallion and you are done.
