In a medium bowl stir boiling water into cornmeal to make a stiff mush. Stir in milk until smooth; then stir in fresh or frozen corn, egg, and the 1 tablespoon chives. Add flour mixture and stir just until combined.
In a large skillet heat 2 tablespoons of the oil over medium heat. Drop batter by rounded tablespoons into hot oil. Cook for 3 to 4 minutes or until golden brown, turning once. Transfer to a serving platter; cover and keep warm.
Repeat with remaining batter, adding the remaining 1 tablespoon oil.
Meanwhile, if desired, stir the 1 teaspoon chives into the sour cream. Serve sour cream with the corn cakes. Makes 6 side-dish servings.
