In a small bowl, stir together yogurt, honey, and cardamom. Cover and refrigerate until ready to serve.
In a medium bowl, stir together sweet potato, egg, flour, curry powder, and salt.
Place a 2-inch ring mold on a small baking sheet. Press approximately 1½ tablespoons sweet potato mixture into mold. Carefully remove mold. Repeat with remaining sweet potato mixture to form 12 latkes.
In a large cast-iron skillet, heat 1 tablespoon oil over medium heat. In batches, gently transfer latkes to skillet. Fry until golden brown and crispy, 3 to 4 minutes per side, adding additional oil as necessary. Drain latkes on paper towels.
Serve immediately with a dollop of yogurt mixture.
Garnish with chives, if desired.
