Lemongrass is a herb looked like grass and widely use in Vietnamese cooking as well as medical. It has a light, fresh, citrus aroma with earthy undertones. We can buy it fresh or frozen at any Oriental stores. I hardly cooked with frozen one. A medium size stalk is yield about 3-4 Tablespoons.
They can be sold by weight or by bundles. If you can pick- medium size is best. These are not too fresh but still good to use.
Trim the stem ends, remove dry,brownist, bruises outer layer.
Chop the stem ends higher if needed. Discard tough stem ends.
Trim off the the leaves below the connections between leaves and stem and discard.
Cut the stems up to 6 inches. Save the tops for making soup.
