In a medium saucepan, melt 3 tablespoons of the butter over medium-low heat with the fresh sage leaves. Once the butter is melted and fragrant, stir in the garlic and shallot and cook gently until it's pretty fragrant, about 30 seconds to 1 minute. Don’t let the garlic brown.
4 tablespoons unsalted butter, 4-5 fresh sage leaves, 2 cloves garlic, 1 teaspoon worcestershire sauce, ½ shallot
Whisk in the flour and let it cook for about 2 minutes, stirring constantly.
3 tablespoons all-purpose flour
Start pouring in the broth a little at a time, whisking constantly. It’ll seize up at first, but as you keep adding liquid and whisking, it’ll smooth out into a thick, creamy base. Don’t forget to whisk into the corners of the pan. Once it’s smooth, add in the apple cider and cider vinegar.
2 cups low sodium turkey broth, ¾ cup apple cider, 2 teaspoons apple cider vinegar
Bring the gravy to a gentle simmer over medium heat. If it starts bubbling hard like a boil, lower the heat. Let it cook for about 10 minutes, stirring occasionally, until it’s thick enough to coat the back of a spoon. You should be able to swipe a finger down the spoon and see a clean line.
Once it’s thickened, taste and season with salt, pepper, and the Worcestershire or a pinch of MSG if you're using it. Taste again to make sure it's right where you want it. Off the heat, stir in the last tablespoon of butter for a silky, restaurant-style finish.
Kosher salt and freshly cracked black pepper
Pour the gravy through a fine mesh sieve into your gravy boat or serving dish to remove the sage leaves and any stray lumps. Serve warm and enjoy!
