To make the brine, juice 1 orange and 1 lemon. Add the water, salt, citrus juice, peppercorns, and bay leaves to a medium saucepan. Warm gently over medium heat, stirring to dissolve the salt, then turn it off. Allow it to cool completely. Note that you will make more brine than you need.
Place the turkey breast in the Zip Top large dish. Pour the brine over the turkey just until it’s covered completely, and discard the remaining brine.
Zip the container shut (pour some brine out if you need to) and set upright in the refrigerator. Allow the turkey breast to brine for at least 3-6 hours, up to 24 hours. Drain the brine and pat the turkey dry with paper towels.
Rub 2-3 Tablespoons of ghee or oil all over the turkey breast, working it under the skin with your hands. Season with salt and pepper. Optionally, season with additional 1/4 teaspoon dried rosemary.
