In a large bowl, add 1/2 teaspoon light soy sauce, 1/2 teaspoon dark soy sauce, 1/2 teaspoon chicken powder, 1/4 teaspoon curry powder, 1/2 teaspoon Jimmy's sate sauce and 2 teaspoons potato starch. Add 1 large chicken breast, sliced into 6 strips and mix thoroughly until evenly coated. Cover and set aside in the fridge for at least 1 hour, or overnight. Twenty minutes before you want to cook, put 6 small bamboo skewers in cold water and leave them to soak, to prevent them from burning during cooking. Thread each chicken strip onto a bamboo skewer, piercing chicken several times to ensure it's securely held on the skewer.
