Well, tis worth growing not only for thai dishes but according to the chef-ette Sophie Grigson, when you make home made lemonade, make a syrup up with ginger slices, crushed lemon grass stems, sugar and water leaving it to simmer gently for about 10 or so mins, then add the strained syrup to the juice of a couple of lemons and some fizzy water. Grown up lemonade she reakons...to be grown up for me I would need a slug of something boozy :P, but that's just little ole me......hic ::)
