Clean, wash and slice the chillies lengthwise, remove the seeds and cut into rings. Put lentils in a sieve, wash thoroughly until the water remains clear. Put lentils, coconut milk, chilli, 100 ml water and turmeric in a pot, cover and bring to the boil. Cover and cook for 12-15 minutes at low heat. Peel and chop the onions. Heat clarified butter in a second pot, fry onions, curry leaves, pandan leaves, cinnamon and lemongrass until brown.
Put half the onions aside for garnishing. Add the cooked lentils, add another 150 ml of water, bring to the boil and simmer for about 5 minutes. Season to taste with salt, sugar and turmeric. Sprinkle with remaining onions and garnish with mint. Delicious with Roti breads
