Horse gram is ground and added to idli batter to make horse gram idlis, a very old Konkani breakfast. My mom has fond memories of her granny cooking this up for them. Traditionally, these horse gram idlis are steamed in a steamer lined up with banana leaves like in the images below. All the batter is poured into the steamer lined with banana leaves. After steaming, you then cut it into tiny pieces while serving. They are called as kulitha rononu in Konkani. Traditionally, horse gram idlis are also made by steaming them in jackfruit leaves baskets. They are then called kulitha khotto in Konkani. That way these idlis have a divine taste and smell from banana leaves/jackfruit leaves.
