I have found that the following ratios work best. If you use too much marinade, it makes the chicken too wet when you try to bread it. And when it comes to breading, you don’t want too much, or bits of it fall to the bottom of the pan and burn. It also means that your breading is too thick and won’t get that crispy, crunchy texture you are looking for. Here are my ideal ratios: ~ 1/3 cup of yogurt or buttermilk per 1.5 lbs of chicken ~ 3/4 cup of some sort of flour for each pound of chicken
