1Tsp of kosher salt per pound of chicken in a gallon ziplock bag. Fill halfway with COLD water and add 1/4 cup of apple cider vinegar.

Mix until salt is dissolved then add the chicken. Fill the rest of the bag until the chicken is covered, remove the remaining air and seal the bag.

Stick the bag in the fridge for 4-8 hours, then remove rinse and pat dry. Then prep and cook as you see fit.

Contrary to popular belief, you CAN over-brine. If you leave the chicken in the brine for too long it can change the texture of the meat and make it rubbery (especially if you add any acid like vinegar or lemon juice). Once that happens most people end up overcooking the meat to firm up the texture.
