Chilled Red Pepper Soup with Sumac, Basil, and Lemon Yogurt
This refreshing chilled purée wakes up your palate with a jolt of sweet pepper essence, cooling yogurt, and the ubiquitous Middle Eastern spice sumac. Sumac is made from the dried berries of a sumac tree, and in the Middle East it’s sprinkled over everything from kabobs to yogurt to rice. The dark-crimson powder lends an acidic, lemony flavor to this soup.
