Questions on frying Chicken breasts
Brining chicken doesn't take more than an hour.Just make sure it is well dried before frying.  I use 1 pint of water with 1/8 cup of salt and the breast (which can be very dry when just fried) comes out juicy,  Hope this helps.
Seasoning should be coated with seasoning but be careful of the salt.  Brining adds some water to the breast but also some salt.
