Start with cold ingredients. Keep your ground turkey in the refrigerator until you're ready to use it. Cold meat is easier to work with and produces better texture.
Mix the seasonings first. In a small bowl, combine all the dry herbs and spices (sage, thyme, garlic powder, onion powder, salt, pepper, rosemary, nutmeg, and red pepper flakes if using). This ensures even distribution.
Prepare the wet ingredients. In another small bowl, mix the olive oil, maple syrup (if using), apple cider vinegar, and ice water.
Combine everything gently. Place the ground turkey in a large bowl. Sprinkle the seasoning mix evenly over the meat, then drizzle with the wet ingredients.
Mix with a light touch. Using clean hands, gently fold and mix the ingredients just until combined. Overworking will make your sausage tough, so channel your inner pastry chef and be gentle.
Make a test patty. Before shaping all your patties, make one small test patty to check the seasoning. This is your insurance policy against a bland breakfast!
Cook the test patty. Heat a skillet over medium heat with a teaspoon of oil. Cook the test patty for about 3 minutes per side until browned and cooked through (internal temperature of 165°F).
Taste and adjust. Try your test patty and adjust the seasoning mix as needed. More salt? More herbs? Now's the time to make it perfect.
Form the patties. Using slightly wet hands (to prevent sticking), portion the meat mixture into 12 equal balls, then gently flatten each into a patty about ½-inch thick. Make a slight depression in the center with your thumb to prevent the patties from puffing up during cooking.
Cook in batches. Heat your skillet over medium heat with a bit more oil. Cook patties in batches (don't crowd the pan!) for about 3-4 minutes per side until golden brown and cooked through.
Rest briefly before serving. This allows the juices to redistribute throughout the meat for maximum flavor.
