Before You Begin

Do not substitute other varieties of lentils here; red lentils have a much different cooking time and consistency. Be sure to double bag the lentils to protect against seam failure. For more about sous vide cooking, refer to our sous vide guide.

Why This Recipe Works

Dal is a class of soups or stews native to the Indian subcontinent made from split beans, lentils, peas, and other legumes. Since red lentils break down relatively easily, we chose them for our take on sous vide dal. First, we tried cooking them for just a couple hours in a hot bath. This yielded evenly cooked and tender lentils—but when we poured them out of the bag, the overall texture wasn't quite right. These lentils were cooked, but still fully intact and the liquid was watery. Fortunately, we found a simple solution: whisking. Whisking the mixture briefly after cooking broke down the lentils, thickened the mixture, and resulted in the ideal consistency—porridge-like but still loose. After a bit more trial and error, we pared down the spice blend to a combination of coriander, cumin, cinnamon, turmeric, cardamom, and red pepper flakes. To brighten the dish, we added chopped fresh tomatoes and cilantro plus a little butter to replicate some of the flavors typically provided by ghee.
