The kaffir lime is a tropical fruit highly prevalent in Indonesia, Thailand, Malaysia, and the Philippines. The kaffir plant is a thorny bush with uniquely curved leaves that grows up to 35 feet tall.
The kaffir lime fruit itself is tiny, measuring just approximately 4 cm in diameter. The kaffir lime is lime green in hue with a rough bumpy skin that turns yellow as it ripens.
In Thai tradition, the fruit is used for a variety of physical and spiritual healing uses in addition to cooking. It’s not uncommon to find a Kaffir lime inside a Thai home because it’s thought to fend off evil spirits!
