The Perks: Cara caras contain lycopene (an antioxidant that may protect against certain cancers) and, like other citrus, flavonones. A recent study found that women who consumed the highest amounts of flavonone-rich citrus had a 19 percent lower risk of clot-related stroke.
The Prep: Try this dish from Cindy Pawlcyn, author of Cindy's Supper Club. Peel six cara caras and slice into rounds. Add 6 thin red onion rings, 8 shredded mint leaves, juice from 1 lime, 2 Tbsp. olive oil, and salt and pepper.
