In a small bowl, combine the garlic powder, onion powder, sugar, allspice, thyme, salt, nutmeg, cinnamon, black pepper, white pepper, ginger, and cayenne. Stir well. Transfer 1/4 cup of the seasoning to a large bowl and 1 tablespoon to a small bowl. Reserve the remainder in an airtight container for another use.
