In medium mixing bowl, whisk together the vegetable oil, sugar, thyme, salt, allspice, paprika, garlic powder, onion powder, cayenne, ginger, cloves, cinnamon and black pepper until a paste forms.
Preheat the oven to 400°F and arrange racks so that you can fit a baking sheet on each in the lower third and middle of the oven. Line two large baking sheets with aluminum foil or parchment paper. Set aside.
