Select and wash the nice looking lentils. Put the lentils in a saucepan and cover with water. Simmer for approximately 30 minutes until the lentils are tender. Meanwhile, crush the roasted “massalé” together with the garlic, cooking salt, chilli, ginger and pepper seeds. Heat the oil in a saucepan. Lightly brown the cumin, 1pinch of mustard seeds, “caloupilé” and chopped onion. Stir from time to time to avoid burning. Add the rest of the spices. Pour over the lentils and stir gently. Allow to simmer for 10 minutes.
