A turkey injection marinade and rub is a good recipe for an injector marinade. To make it, gather 1 cup chicken broth, 1/2 cup melted butter, 1 cup softened butter, 1/2 cup lemon juice, 1 clove garlic (minced), 2 small cloves garlic (minced), 1 teaspoon ginger (minced), 1 teaspoon English mustard powder and 1 turkey (14 lbs). Additionally, you need 2 sprigs thyme (chopped), 3 sprigs rosemary (finely chopped), 1 pinch salt and ground pepper and 1 tablespoon olive oil.
To create the marinade, combine the chicken broth with the lemon juice, English mustard powder, 1/2 cup melted butter, 1 clove garlic and ginger in a bowl and stir the mixture together. Cover the bowl with plastic wrap and refrigerate for at least 30 minutes. This gives the flavors a chance to blend.
To make the rub, combine 1 cup softened butter with the rosemary, thyme and two small garlic cloves in a separate bowl. Mix as evenly as possible.
Separate the skin of the turkey from the meat by carefully running your hand under it. Using a spoon, spread the rub mixture evenly under the skin around various parts of the turkey.
Pour the marinade into an injector and inject it into the fleshiest parts of the turkey. Change the angle of the needle at various times to hit as many areas as possible.
Use a brush to spread the olive oil around the turkey and season it with salt and pepper. Place the turkey in a large pan and cover it with plastic wrap. Refrigerate the turkey for 12 to 24 hours before serving.
Prep time for this recipe is around 20 minutes. It should be ready to serve in 12 to 13 hours.
