Lemongrass
Lemongrass is a tropical perennial grass prized for its intensely fragrant, lemony aromatic profile that dominates Southeast Asian cuisine. The white and light green inner bulbous portions are the primary culinary parts, offering a fresh, slightly sweet citrus flavor without the acidity of lemon. Essential in Thai, Vietnamese, and Malaysian cooking, lemongrass adds complexity and brightness to curries, soups, stir-fries, and beverages. Its versatility extends from savory dishes to teas and cocktails, making it indispensable in modern fusion cuisine.

Origin & Heritage
History
Native to tropical regions of Southeast Asia, lemongrass has been cultivated for centuries in Thailand, Vietnam, and Malaysia for both culinary and medicinal purposes. The herb spread globally during the 20th century spice trade expansion and increased interest in Asian cuisines, now widely cultivated in tropical and subtropical regions worldwide including India, West Africa, and the Caribbean.

In Southeast Asia, it symbolizes hospitality and is integral to ceremonial dishes and family-passed recipes spanning generations. The herb also features prominently in traditional Ayurvedic and Chinese medicine systems.
The Science
Understanding the key chemical compounds helps explain why lemongrass pairs well with certain ingredients.
Primary aromatic compound (60-80% of essential oil) responsible for intense lemon-lime aroma and flavor; provides antimicrobial and anti-inflammatory properties
