Lemongrass
Lemongrass is a aromatic tropical grass with a distinctive bright lemon flavor and subtle herbaceous notes, essential to Southeast Asian cuisine. The plant consists of pale green and white stalks that contain the most flavorful oils concentrated in the lower 6-8 inches. Fresh lemongrass is prized for its ability to impart citrusy complexity to both savory and sweet dishes without the acidity of lemon juice. Its versatility spans from aromatic broths and curries to teas and cocktails.

Did You Know?
- 1.Lemongrass gets its citrus aroma from citral, the same compound found in lemon peel, yet it contains no actual citric acid, making it ideal for those who need citrus flavor without acidity
- 2.A single lemongrass plant can be harvested repeatedly by cutting outer stalks from the base, allowing it to regenerate and produce for 3-4 years, making it economical for home gardeners
- 3.In traditional Ayurvedic and Southeast Asian medicine, lemongrass tea is believed to have fever-reducing properties, earning it the nickname 'fever grass' in many regions
- 4.The botanical name Cymbopogon citratus comes from Greek words meaning 'sword beard' (cymo = sword, pogon = beard) referring to the grass-like appearance of its blade-like leaves
- 5.Lemongrass is completely different from citronella, despite sharing the name 'citronella grass'; citronella comes from a different plant and is used in insect repellents rather than cooking
