Place the leftover rice in a large mixing bowl. Gently mash it with a spoon or fork to form a smooth, slightly sticky paste. Avoid over-mashing to keep some texture for crispier pakoras.
Add grated carrot, shredded cabbage, chopped coriander, chilli, and ginger to the mashed rice. Mix well so the vegetables are evenly distributed, giving every pakora a balanced flavour.
Sprinkle cumin powder, chaat masala, Kashmiri chilli powder, salt, and crushed pepper. Add the gram flour and knead gently. The besan binds the mixture, making it easier to shape into pakoras.
Take small portions of the mixture and form bite-sized fritters or your preferred shape. Ensure the thickness is uniform for even frying.
In a deep frying pan, heat oil on a medium flame. Test by dropping a small piece of batter—if it rises steadily and bubbles, the oil is ready for frying.
Carefully drop the shaped pakoras into the hot oil. Fry in batches, stirring occasionally to prevent sticking. Cook until golden brown and crisp on all sides. Remove with a slotted spoon and serve hot with tomato sauce, green chutney, or ketchup for a perfect tea-time snack.
