In a small bowl, combine the salt, pepper, dried sage, garlic powder, brown sugar, and cayenne pepper. This ensures the spices are evenly distributed throughout the meat rather than clumping in one spot. In a larger bowl, add the ground turkey and drizzle with olive oil, then sprinkle the seasoning blend over top. Using your hands, gently mix until just combined—work quickly and don't overmix, as this can make the sausage dense and tough. I find that chilling the mixture for 10-15 minutes makes it easier to form into patties.
