These green limes (Citrus lima) are also known as “real” limes – and can’t be mistaken for “normal” yellow limes. Known everywhere as a main ingredient in the Caipirinha (Brazil’s national cocktail), they are prized for their powerful “well-rounded” acidity. These limes are rich in vitamin C and also have, among other things, vitamin B1, magnesium, potassium, and valuable Omega fatty acids. Lime juice adds a refreshing, crisp finish to any smoothie.
