This yumalicious dish is Mrs. Chanchal Kapoor's Village-Style Carrots with Potatoes and Peas (Gajar Aloo Matar) from Madhur Jaffrey's World Vegetarian cookbook. According to the book: "A dish from the villages of the Punjab in northwestern India, this is cooked up in open courtyards in the morning and then taken to the farmers in the fields at midday, along with breads, pickles, and yogurt or fresh buttermilk." We have several cookbooks by Madhur Jaffrey, and I don't think there is a bad dish in any of them.
Um, yum (this was cooked by B., of course!). Gotta go: I'm really hungry now!
