Thaw your turkey completely — allow about 24 hours for every 5 pounds.
Add all ingredients, including the lemon slices, to a large pot.
Bring to a boil and cook for about 20 minutes, until the salt and sugar are dissolved.
Let the brine cool to room temperature, or add ice to chill quickly.
Refrigerate until the brine is completely chilled.
Open the thawed turkey, remove the neck, gravy packet, and giblets, and rinse the bird thoroughly.
Place the turkey breast-side down in the brine, ensuring it’s completely covered (fill the cavity too).
If the brine doesn’t fully cover the turkey, make more using 4 tablespoons of salt for every 4 cups of water.
Keep the turkey submerged by placing a plate or weight on top if needed.
Brine in the refrigerator for 12–24 hours.
After brining, drain, rinse, and pat dry the turkey thoroughly.
For best results, let the turkey rest uncovered in the fridge for 1–2 hours before cooking for crispier skin.
