Add the carrots and the dried red lentils. Turn up the heat, bring the pot to boil and once boiling, turn down the heat and allow it to simmer until the lentils are completely soft/mushy. I keep an eye on it and use a wooden spoon to avoid the dhal from burning at the bottom of the pot. Once the lentils are mostly done (about 20 minutes), add a cup or two of water based on the consistency you’d like.
