How boring would the world be without lemons? Prized for centuries, this fruit was traded for valuables in places all over the world. Lemons perk up humdrum dishes and their delightful tang is a welcome addition to appetizers, breads, main courses, desserts, and drinks. Use lemon juice as a substitute for vinegar and sprinkle on fruit to prevent browning or discoloration. High in dietary fiber, vitamin C, vitamin B6, calcium, potassium, riboflavin, and iron, lemons have it all. So, pucker up!
