I used to make this on the stove top all the time, but now I prefer to use
the Instant Pot. Whip up a batch whenever you have a few minutes to spare, and it will stay piping hot until you’re ready to enjoy it. The soup is brightly flavored from the squeeze of lemon juice stirred in at the end of cooking. That addition really makes the dish, so don’t skip it! Serve the soup drizzled with extra-virgin olive oil and sprinkled with sumac (a lemony Middle Eastern spice) for a fresh, peppery finishing touch.
