1. Brine Turkey
Combine the water, salt, 1 cup bourbon, 1/2 cup sugar, the orange, and peppercorns in a large pot. Bring to a simmer, whisking to dissolve the salt and sugar. Remove from the heat and let cool to room temperature.
If needed, transfer the brine to a vessel that will fit in the refrigerator. Add the turkey breast halves, cover, and chill for at least 8 hours but no more than to 12.
