The limetta, or Mediterranean sweet lemon, is a pale, low-acid citrus grown around the Mediterranean and across the Middle East for eating fresh and juicing. Lemon-shaped and yellow-skinned but almost free of sourness, it tastes gently sweet, soft and faintly floral — a lemon with the tartness turned off. In Iran it is the beloved limu shirin; in Italy the ornamental, gnarled forms are known as lumia; in the Levant it is a everyday sweet lemon, pressed for a mild, refreshing juice reputed to be soothing and easy on the stomach.
