- Preheat a grill to medium (about 350 degrees F) on one side. Pour the beer into a turkey sitter (a ceramic stand that holds liquid). Or open the beer can, pour out a few tablespoons and place in a beer-can turkey stand.
- Combine the mustard powder, garlic powder, dried onion, paprika, granulated garlic, cumin, and salt and pepper to taste in a small bowl.
- Remove the neck, giblets and any excess fat from the turkey; discard. Rinse the turkey under cold water and pat dry with paper towels. Rub the cavity with 2 to 3 teaspoons of the spice mixture. Brush the outside of the turkey with the canola oil and place drumstick-end down on the sitter or stand. Rub the remaining spice mixture all over the turkey.
- Place the turkey (on the sitter or stand) on the cooler side of the grill. Cover and cook until the juices run clear and a thermometer inserted into the thickest part of the thigh registers 185 degrees F and 170 degrees F in the breast, 2 to 3 hours. Carefully remove the turkey from the grill, remove from the sitter or stand, and discard the beer. Transfer the turkey to a cutting board and let rest at least 20 minutes before carving.
