Add the diced / grated carrot to a saucepan with the red lentils, and add plenty of water. Bring to a boil, and cook for about 5 minutes, until the lentils are about half cooked (they should be soft enough to eat, but still with a bit of bite, and still holding their shape).

Drain the carrot and lentil mixture, and transfer it to a food processor. Blitz until a paste is formed. Transfer the mixture to a large bowl, and add the remaining ingredients (except the oil). Mix well.

Heat the oil in a large frying pan, and add dollops of the lentil mixture (don't worry about shape). Don't overcrowd the pan - you may need to do a couple of batches. Cook the koftas for a few minutes, until the underside is golden brown and crispy, then gently turn each kofta over, and repeat. Continue to turn until they are golden brown on all sides.

Serve with curry sauce and more fresh coriander.
