Prepare the Chicken: Start by cutting the chicken thighs into smaller pieces then adding them to a bowl and season with the black pepper. To a small bowl, add the garlic paste, ginger paste, soy sauce, sesame oil and brown sugar then mix them together.
Pour the marinade onto the chicken and mix well to coat all the chicken. Cover and store in the fridge for 30 minutes. Remove the chicken from the fridge and add the egg white. Mix the egg white into the chicken then sprinkle on the cornflour. Mix the cornflour into the chicken and ensure all the chicken is coated well with cornflour.
Place a heavy duty pan on a medium to high heat and add the oil. Once the oil starts to sizzle, add in the chicken and cook for around 10 minutes. Turn the chicken occasionally to ensure each piece is brown on both sides. Once cooked, the coating should be crispy and golden brown in colour. The internal temperature should be a minimum 72oC. Remove the chicken using a slotted spoon and place on a plate lined with kitchen towel.
Make the Sauce: To a small bowl, add the sriracha sauce, tomato ketchup, honey and lime then stir and set aside. Place a frying pan on a medium heat and add the sesame oil. Add in the chopped garlic, spring onion, red chilli and ginger. Cook for 2 minutes whilst stirring. Pour the sauce into the pan, stir and allow to simmer for 1 minute. Add the chicken to the sauce and coat the chicken in the sauce. Remove the chicken from the heat and set aside.
Make the Noodles: If using dried noodles, place a saucepan of boiling water on a high heat. Once the water is boiling, add the noodles and cook or soak for the time on the packaging. Strain the noodles, rinse with cold water and set aside. If using cooked noodles then skip this step.
Place a non-stick frying pan on a medium to high heat and add the oil. Add in the onions, red peppers and green peppers then cook for 2 minutes. Add in the julienne carrots then toss in the cooked noodles and stir fry for 1 minute. Pour in the soy sauce, oyster sauce and mix until combined. Remove from the heat and serve the noodles with the crispy sweet chilli chicken.
