Step-by-Step Instructions

Step 1: Prepare the Chicken

Cut chicken into bite-sized chunks.

Season lightly with salt and white pepper.

---

Step 2: Coat the Chicken

Set up breading station:

1. Bowl 1: Cornstarch + flour
2. Bowl 2: Beaten eggs

Dip chicken in egg, then dredge in cornstarch-flour mixture.

Press coating firmly for maximum crispiness.

---

Step 3: Fry Until Golden

Heat oil to 350°F (175°C).

Fry in batches 4–5 minutes until golden and cooked through (internal temp 165°F / 74°C).

Transfer to wire rack (not paper towels — prevents sogginess).

---

Step 4: Make the Sauce

In a saucepan over medium heat, combine:

• Sugar
• Vinegar
• Ketchup
• Soy sauce
• Pineapple juice

Bring to gentle simmer.

Stir in cornstarch slurry and cook until thick and glossy.

The sauce should coat the back of a spoon.

---

Step 5: Stir-Fry Vegetables

In a large skillet or wok:

• Sauté bell peppers and onions 2–3 minutes.
• Add pineapple chunks.

Vegetables should remain slightly crisp.

---

Step 6: Combine Everything

Add crispy chicken to skillet.

Pour sauce over and toss quickly to coat.

Serve immediately for best texture.

4. Bake 20–25 minutes until crispy and cooked through.

Toss with sauce before serving.

Texture will be slightly less crisp than fried but still delicious.

Coat with sauce just before serving.

Chicken thighs remain moist even after frying.

Prevents oil temperature drop.

3. Keep Sauce Separate Until Serving

Maintains crisp texture.

4. Double Fry for Extra Crunch

Fry once, rest 5 minutes, fry again briefly.
