Ingredients
- 360 g boneless chicken thighs
- 1.5 tbsp light soy sauce
- 0.5 tbsp rice wine
- 0.25 tsp sugar
- 0.5 tsp white pepper powder
- 14 head green cabbage
- 3 tbsp mayonnaise
- 3 cloves garlic
- 0.5 tbsp fish sauce
- 2 tsp sugar
- 0.25 tsp sweet paprika
- 1 lime (for zest and juice)
- 1 tsp Sichuan peppercorn oil
- to taste corn starch
- to taste olive oil
- 2 slices sourdough bread
- optional fresh cilantro
- optional Birds eye chilies
- optional toasted crushed peanuts
Instructions
- 1Prepare the cabbage

Take a quarter wedge of a washed green cabbage and place it on a clean cutting board. Using a sharp chefs knife or a peeler, finely shred the cabbage into thin, uniform strips. This shredded cabbage will provide a crisp, refreshing contrast to the savory chicken.
Tip: Ensure the shreds are as thin as possible to maximize the surface area for the icy soak to work its magic. - 2Soak in ice water

Transfer the finely shredded cabbage into a large glass bowl filled with cold water and ice. Use your hands to submerge and mix the cabbage thoroughly. Let it soak for about 10 minutes to remove any raw bitterness and achieve a superior crunchy texture.
Tip: The ice water bath is the key to achieving that restaurant-quality snap in the cabbage slaw. - 3Spin the cabbage dry

Drain the cabbage and place it into a white salad spinner basket. Spin vigorously to remove all remaining water. It is essential that the cabbage is perfectly dry before assembly to ensure it stays crunchy and doesnt dilute the flavors of the sauce.
Tip: If you dont have a salad spinner, wrap the cabbage in a clean kitchen towel and shake it well to remove moisture. - 4Score the chicken thighs

Lay the boneless chicken thighs on a wooden cutting board. Using a sharp knife, make shallow scores across the surface of the meat. This helps the marinade penetrate more deeply and allows the chicken to cook through more evenly in the pan.
Tip: Scoring the meat also prevents it from shrinking or curling too much during the frying process. - 5Add the marinade

Place the scored chicken thighs into a shallow ceramic bowl. Pour in the light soy sauce, rice wine, sugar, and white pepper powder. These ingredients form the savory and aromatic base for the Taiwanese-style pepper seasoning.
Tip: White pepper provides a unique floral heat that is essential for authentic pepper chicken flavor. - 6Marinate the meat

Use your hands to massage the seasonings into the chicken thighs, ensuring every part is well-coated. Let the chicken marinate for at least 30 minutes to allow the flavors to fully develop and penetrate the meat.
Tip: For the best results, cover the bowl and let the chicken marinate in the refrigerator. - 7Start the sandwich sauce

Begin the dressing by squeezing three tablespoons of mayonnaise into a small glass bowl containing two to three cloves of minced garlic. This creamy base will act as the foundation for the spicy and zesty Taiwanese-style sauce.
Tip: Using a squeeze bottle for the mayonnaise helps with precise measurement and keeps the workspace clean. - 8Prepare the pepper sauce

In a glass bowl, combine mayonnaise, minced garlic, fish sauce, sugar, sweet paprika, lime zest, lime juice, and Sichuan peppercorn oil. Use a spoon to stir the ingredients thoroughly until they are fully emulsified into a smooth, creamy dressing with a light orange tint.
Tip: The Sichuan peppercorn oil provides a signature numbing heat; add it gradually to find your preferred spice level. - 9Coat the chicken in starch

Take each marinated chicken thigh and press it firmly into a plate of cornstarch. Make sure the meat is completely and evenly coated on all sides, as this starch layer is essential for creating a signature crispy, golden-brown crust.
Tip: Let the coated chicken rest for five minutes before frying; this helps the starch adhere better and prevents it from falling off in the pan. - 10Heat the frying oil

Place a light-colored frying pan over medium-high heat and pour in a generous amount of olive oil. Swirl the pan to ensure the bottom is evenly coated. Using a light pan allows you to better monitor the color of the chicken as it fries.
Tip: Wait until the oil is shimmering and hot before adding the chicken to prevent the coating from absorbing too much oil. - 11Fry the chicken

Carefully place the prepared chicken thighs into the hot oil, skin-side down first. You should hear an immediate sizzle. Fry the pieces without overcrowding the pan to ensure the temperature stays high for maximum crispiness.
Tip: Always lay the chicken away from your body when placing it in the hot pan to avoid any oil splashes. - 12Flip for a golden crust

Once the skin side is deeply golden and crispy, use tongs to flip the chicken thighs over. Continue to fry the other side until it is equally browned and the chicken is fully cooked through and juicy on the inside.
Tip: Avoid flipping the chicken too early; let it develop a solid crust first so the coating doesnt tear or stick to the pan. - 13Sauce the toasted sourdough

Take a slice of freshly toasted sourdough bread and spread a generous layer of the prepared pepper sauce across the surface. Ensure the sauce is distributed evenly to the edges to provide a flavorful, creamy base for the cabbage and chicken.
Tip: Toasting the bread well creates a sturdy base that wont become soggy once the sauce and fresh toppings are added. - 14Add the shredded cabbage

Pile a large amount of the chilled, finely shredded cabbage slaw onto the sauce-covered bread. The cabbage should be completely dry to maintain its signature crunch and provide a refreshing, cool contrast to the spicy sauce.
Tip: Soaking the shredded cabbage in ice water for 10 minutes before drying makes it extra crispy and removes any bitter raw taste. - 15Slice the crispy chicken

Place the golden-brown fried chicken thighs on a wooden board and slice them into uniform strips. The exterior should be audibly crispy and well-browned, while the interior remains tender, juicy, and fully cooked through.
Tip: Let the chicken rest for a few minutes before slicing to keep the juices inside and ensure the crispy skin stays attached to the meat. - 16Assemble and garnish

Carefully transfer the sliced crispy chicken cutlets and arrange them over the cabbage slaw. Generously drizzle with the remaining sauce, then garnish with chopped cilantro, red chili peppers, and crushed peanuts. Squeeze a fresh lime wedge over the top for a bright finish.
Tip: Serve the sandwich immediately after assembling so the warm meat and chilled slaw provide the ultimate textural contrast.
