Kaffir Lime: A Global Journey of Fragrant Aroma
The kaffir lime, a small, knobby fruit native to Southeast Asia, may not be a global superstar like its citrus cousins, but its impact on the culinary world is undeniable. Beyond its fragrant leaves and zest that grace Thai curries and Indonesian soups, kaffir lime boasts a fascinating production journey spanning continents and cultures.
Production Powerhouses:
While widespread cultivation occurs throughout Southeast Asia, three countries dominate the global kaffir lime scene:
Thailand: The undisputed king of kaffir lime production, Thailand boasts vast plantations producing over 40,000 tons annually. Its proximity to major markets and focus on organic farming make it a key player.
Indonesia: With around 25,000 tons of yearly production, Indonesia plays a crucial role, particularly in supplying neighboring islands and catering to its own vibrant culinary traditions.
Vietnam: Growing steadily, Vietnam contributes around 10,000 tons annually, catering to domestic needs while also exporting to countries like France and the United States.
