Method

• 01
  Whisk the soy sauce, sake and ginger together in a bowl to combine.
• 02
  Add the chicken and mix well to ensure each piece of chicken is coated with the marinade. Cover and refrigerate, allowing the chicken to marinate for at least 1 hour or up to 4 hours.
• 03
  When you are ready to fry the Kgarage, add 1 inch of vegetable oil in a heavy-bottomed pot and heat until the oil reaches 340 degrees F (170 C). Prepare a paper towel-lined rack. While you wait for the oil to come up to temperature, dredge the marinated chicken in potato starch to coat each piece evenly and set the pieces of coated chicken on a tray.
• 04
  When the oil ready, fry the coated chicken in batches. Don't overcrowd the pot, and I recommend batching pieces of chicken that are roughly the same size. Karaage frying in oil in a cast-iron pot. When the karaage hits an internal temperature of 160 degrees F (71 C), transfer them to the prepared rack and let them rest for a few minutes before serving them.
