Which side should the chicken breast face when stacking in the marinator?

When stacking chicken breasts in the marinator, it is important for the bone side to face down. This orientation allows for better drainage of any excess marinade and promotes even marination. When the bone side is facing down, the juice and flavor from the marinade can fully permeate the meat without being trapped or pooling at the top, which can happen if the skin side or flesh side is facing down. Additionally, having the bone side down helps maintain the structure of the chicken, preventing it from becoming damaged or overly compressed during the marination process. This technique ensures that the chicken is properly seasoned throughout, leading to a better final product when it is cooked.
