The Meyer lemon is a unique variety of citrus fruit that is thought to be a cross between a citron and a mandarin/pomelo hybrid. Originating from China, it’s distinguished by its round shape and deep yellow, slightly orange-tinted skin when ripe. Unlike the more common lemon varieties, the Meyer lemon has a sweeter and less acidic flavor, making it a favorite for culinary uses and ornamental purposes. It was introduced to the United States in the early 20th century and has since become a popular ingredient in various recipes, thanks to its distinctive taste.
