Dal is hearty and comforting at any time of year, and you can cook a big batch to serve throughout the week. The flavors just keep getting better! Add additional vegetables if you like; just cook them along with the onions until tender. If you don't have tamarind, substitute some fresh lime or lemon juice at the end of cooking to replace its tangy taste.
