Step 1:
Remove each half of the turkey breast by cutting lengthwise along each side of the breastbone.
Step 2:
Pull the first half of the breast away from the breastbone, using a sharp knife to carefully release the meat from the rib cage.
Step 3:
It is much easier to carve a half of a turkey breast into crosswise slices than it is to carve the breast while it is still attached to the body.
