Add the minced onions and garlic. Braise for about 1 minute, then add the ginger pieces and the spices. Braise for another 1 minute (this will allow the spices to develop their flavours).
Pour the water into the saucepan. Rub well the bottom of the pan to dissolve all the spices. Add the lentils.
Bring to boil, then reduce the heat and simmer over low heat for about 20 to 25 minutes, until lentils are cooked.
Remove the ginger pieces and serve it sided with rice or naan bread.
