- Soak the moong dal for 4-5 hours and then drain the water and add to a blender. Blend to form a thick paste. Add little water. Take out the mixture in a bowl. Add salt, asafoetida and dry mango powder. Now add finely chopped onion, tomato, capsicum, green chilli and coriander leaves. Mix well to prepare a batter. Keep whisking for a few minutes until the batter seems a bit frothy. Heat 1 tbsp butter in a small pan. Pour half of the batter into the pan and let it cook for a few minutes. Flip it towards the other side and cook until crispy. Serve the moonglet hot with ketchup.
