In West Bengal's Kolkata, Ajmeri's Bakery near Bow Barracks has baked Christmas treats for nearly 200 years, using a wood-fired oven. Owner Sheikh Khadimul Bashar says, "My family has owned the bakery for seven generations." Famous for fruitcakes and bakarkhanis, the bakery draws festive crowds each December, though rules discouraging wood-fired ovens raise concerns over its future.
