How many skewers of Bone Brothers in a catty is about 12 skewers. Because each string is 40g, one catty is equal to 500g, so it is about 12 strings. Bone-in, a dish with chicken thigh meat as the main ingredient, is marinated with spicy seasoning, flavored with spice and contains no preservatives. Bone-in is a new flavor casual product at KFC, which is fresh chicken thigh meat plus the crispy cartilage from the chicken breast marinated in a special spicy seasoning. There are multiple pieces of cartilage and multiple pieces of chicken on a skewer, which are tumbled, skewered on bamboo sticks, and then baked in a computer-controlled oven through a special process. The flavor is somewhat spicy with a hint of sweetness. The biggest selling point of this Western-style barbecue over the roadside barbecue is hygiene, both barbecue flavor, but not pollute the environment.
