Ingredients

  • Kosher salt
  • 3/4 teaspoon store-bought or homemade garam masala, recipe follows
  • 1/2 teaspoon ground cumin
  • Freshly ground pepper
  • 2 pounds sweet potatoes, peeled, and cut into 1/2-inch slices, then again into 1/2-inch sticks
  • Olive oil
  • 3 large cinnamon sticks (if you have the kind you get at Indian stores, it's about 3 tablespoons of cinnamon bark bits)
  • 3 tablespoons whole cloves
  • 1/4 cup green cardamom pods, shelled, husks discarded (about 2 tablespoons of seeds)
  • 4 large black cardamom pods, shelled, husks discarded (about 1 tablespoon of seeds), optional

Method

  • Preheat the oven to 450 degrees F.
  • In a small bowl, toss together 1 rounded teaspoon of salt, garam masala, cumin and some freshly ground black pepper to taste.
  • Add the sweet potatoes to a large bowl, drizzle with enough olive oil to coat, and sprinkle with the spice rub.
  • Toss well to coat evenly.
  • Pour the sweet potatoes out onto a parchment paper-lined baking sheet or a baking rack, making sure all the pieces are evenly spaced.
  • Bake 30 to 35 minutes, flipping halfway through.
  • Remove the potatoes from the baking sheet and serve immediately.
  • Combine the cinnamon sticks, cloves, green cardamom seeds, black cardamom seeds, if using, in a spice grinder or coffee grinder and grind until fine.
  • Store the spice mix in an airtight container away from direct sunlight.
  • Yield: about 1/2 cup.
