Limes are small, round to oblong citrus fruits, measuring 5 to 7 centimeters tall and 4 to 6 centimeters wide. They have a thin, smooth, glossy green rind that will become a greenish-yellow as it ripens. Volatile oils in the rind produce a citrusy bouquet. The flesh is pale green and can be seedless or may contain several small seeds at its center. The juicy flesh is aromatic, extremely acidic and has a sour citrusy flavor.
Limes are available year-round.
