Put the lentils to soak for at least 30 minutes in fresh water, then drain well. In a saucepan heat the butter (or ‘oil), add the GIA Onion, Ginger, Chilli and Garlic Paste and fry 3 minutes, add the curry according to your taste. Let the spices flavor in the sauté for a minute.
Add the lentils and let them flavor a couple of minutes in the sauce, stirring constantly; pour water until covered with a finger (the water must be about 3 times the volume of the lentils). Cook over medium heat, stirring occasionally, for 30 minutes, or until the lentils are very soft, but not completely undone. Salt and, if necessary, season with spices. Serve with white boiled rice or piadina bread, accompanied with lemon wedges to spray on lentils, to taste.
