Ingredients:
- 1.5 lbs chicken breast, cut into 1-inch cubes
- 1 large egg white, beaten until frothy
- 2 tbsp soy sauce, divided
- 1/2 cup cornstarch
- 1/4 cup all-purpose flour
- 1/2 tsp salt
- 1/2 tsp white pepper
- 3 tbsp high-smoke point vegetable oil (absorbed quantity)
- 1/2 cup pineapple juice
- 1/4 cup rice vinegar
- 1/4 cup ketchup
- 1/3 cup light brown sugar, packed
- 1 tsp toasted sesame oil
- 1 cup pineapple chunks
- 1 red bell pepper, cut into 1-inch squares
- 1 green bell pepper, cut into 1-inch squares
- 1/2 white onion, cut into petals
- 2 cloves garlic, minced
- 1 tsp fresh ginger, grated
Instructions:
- In a medium bowl, toss the 680g of cubed chicken with the beaten egg white and 1 tablespoon of soy sauce. Let marinate for 10 minutes until the meat feels slightly tacky. Note: This is the velveting step that ensures tenderness.
- In a separate shallow dish, whisk together the cornstarch, flour, salt, and white pepper. Dredge each piece of marinated chicken in the starch mixture, shaking off any excess.
- Heat vegetable oil in a large skillet or wok over medium high heat. Working in batches, sear the chicken until the exterior is golden and shattering, approximately 3-4 minutes per side.
- Remove the chicken from the pan and set it aside on a wire rack. Note: Using a rack prevents the bottom from getting soggy.
- In a small jar or bowl, whisk together the pineapple juice, rice vinegar, ketchup, light brown sugar, remaining 1 tablespoon of soy sauce, and sesame oil.
- Wipe the skillet clean with a paper towel and add a fresh splash of oil. Stir fry the bell peppers and onion until they are vibrant and crisp tender, about 2 minutes.
- Add the minced garlic and grated ginger to the vegetables, stirring for 30 seconds until the aroma fills the kitchen.
- Add the pineapple chunks to the pan and toss briefly to warm them through.
- Pour the sauce mixture into the pan and bring to a simmer. Cook for 1-2 minutes until the sauce becomes thick and translucent.
- Return the crispy chicken to the pan and toss quickly until every piece is glossed in red, then serve immediately.
