Lemongrass is a fragrant culinary herb. The herb gives off a gentle citrus scent that smells like lemons. It has a long history in Asian cuisine and can be found in many Thai style soups and curries.
Look for firm stalks and a subtle smell of lemons. Fresh lemongrass should have a solid bulb and the stalks may be pale to vivid green. It is possible for the tops to be slightly dry, just avoid ones that are brown or very dried out.
Cut the top off and trim two inches from the bottom. These parts can be used to make a zesty broth or as a relaxing tea. Now, use your fingers to peel the outer layers until you reach the meaty center. You can chop it up and add it to stir-fry or grate it on top of soups!
