Lemon Barley water is an old fashioned British tonic that was given to the weak as an alternative source of nourishment. Now most people just drink it because they like it! Some recipes use sugar in their recipes however honey gives it a more intense flavor. If you have any fresh ginger handy, finely grate about 1 tablespoon of it and boil it with the barley for a gingery kick. Found on the internet. Enjoy!
