Do different kinds of lentils require different cooking times?
Yes! Brown lentils, which are the most common, can cook in as little as 22 minutes. Green lentils, which are also called Puy or French lentils, are smaller but take at least twice as long to cook –usually about 45 minutes.
Red lentils ,which are sweet mild, take about 30 minutes. Those are often used to make dal: they cook down to a chunky puree.
