I just used low fat mayo and didn't change the rest and it was great.
My entire family loved this flavorful and moist chicken. Because I didn't have Kewpie mayo, I followed a recipe to make 1 cup of it. In stead of cutting a chicken into half, I cut it up into 10 pieces and left it in the marinade for 6 hours. I will definitely make this again. Thank you for a great recipe!
