Lemongrass is a tall-growing, clumping grass that is native to Southeast
Asia and cultivated in other tropical zones. The leaves contain a high
concentration of a compound called citral, which accounts for the herb’s
lemony aroma and flavor. Lemongrass also contains a phytochemical called
citronellol, which is why the herb is also known as citronella grass.
In Asian cuisine, lemongrass is commonly used to flavor teas and
soups. In Indonesia, where the herb is known as sereh, lemongrass is
used to season roasted chicken. In the Philippine province of Cebu,
lemongrass is a key flavoring in lechón, a national dish that consists
of a whole roasted pig.
