Chicken Stock (Best Option)
1 cup per 1 cup chicken brothChicken stock is made by simmering bones and connective tissue, which releases gelatin and rich flavors similar to broth. This gelatin helps retain moisture in the chicken, contributing to juiciness and tenderness.
When using chicken stock, ensure it is well-seasoned or adjust salt accordingly since stock can sometimes be less salty than broth. Avoid overly concentrated stocks that may intensify flavors too much.
The final fried chicken will have nearly the same savory profile and moisture retention as when using chicken broth, making it the most seamless substitute.
