*Cut the root end off the lemongrass and then cut the lemongrass where the white part meets the greener part (you only use the white part, discard the root end and the darker part. Slice the lemongrass piece in half in the length and remove the outside two layers of the lemongrass, this part is too tough, discard. Then chop the white part very finely. You can freeze the rest of the lemongrass for another use, chopped or whole.
