Meyer lemons are a hybrid citrus fruit believed to be a cross between a lemon and a mandarin or orange. They have thin, smooth, deep yellow to orange-colored skin and are slightly sweeter than regular lemons, with a distinctive floral aroma. Meyer lemons also have a lower acidity than regular lemons, making them a popular ingredient in sweet desserts and savory dishes. The Meyer Lemon Tree is typically in season from December through May, while regular lemons are available year-round.
