How to Make It
Preheat oven to 375°F. Place a lightly greased wire rack on a parchment paper-lined rimmed baking sheet. Stir together brown sugar, chili powder, cumin, salt, and cayenne pepper; set aside.
Cut jackfruit into 1/4-inch-thick planks, and place on prepared rack. Brush slices lightly with liquid smoke, and sprinkle with brown sugar mixture, pressing to adhere. Bake until lightly browned and starting to crisp, 25 to 28 minutes.
