Finger limes are small, elongated citrus fruits native to Australia. They are typically about 2 to 4 inches long and come in various colors, including green, yellow, and pink. The unique feature of finger limes is their caviar-like pulp, which consists of tiny, juicy vesicles that burst with a tangy flavor when bitten. These fruits are often used in gourmet dishes and cocktails due to their vibrant taste and appealing texture. Finger limes are rich in vitamin C and antioxidants, making them a nutritious addition to meals. They are sometimes referred to as "citrus caviar" because of their distinctive appearance and culinary uses.
