Line a baking sheet with foil or parchment paper. Set a baking rack on top and set aside.
Remove packing from turkey breast and pat dry with paper towels.
Place the turkey breast, breast side down on your cutting board with the backbone facing toward you.
Now using your kitchen shears, start on one side of the backbone. Cut down along the spine. You'll snip through the ribs and down the spin all the way down the bird. If you get stuck on a bone, simply shift your shears over a little to the left or right to get through. Once one side is free from the spin, repeat the same cut on the other side to release the backbone completely.
Save the backbone for stock later.
Now flip the chicken over ,with the top of the breast facing away from you. Place one hand flat directly in-between the two breast. Place you other hand on top and push very firmly on the breast to flatten. You should hear some of the rib bones crack as they flatten. That's it!
Now to brine the turkey, pull the skin back so the meat is exposed. Pat dry if there's still any surface moisture.
Set aside 1 tsp of salt. Generously sprinkle the remaining salt on top of the meat. Rub to help distribute salt all over the meat.
Pull skin back over the meat. Use remaining teaspoon of salt over the skin.
Transfer the turkey breast to your prepared baking sheet and cover with plastic wrap.
Place in the fridge and allow to sit for 24 hours
After 24 hours removed the plastic wrap and let sit in fridge uncovered for an additional 24 hours so the skin dries out.
