When I was small, my Grandad would make me hot lemon barley whenever I felt a bit sick. He'd make it from concentrate - but I recently found a recipe somewhere on the internet for making it from scratch (something which had never even occurred to me as possible before) and I have been making and enjoying jars of it pretty much every day since. I thought I would share this because its so ridiculously easy I can't even believe it. Also, for once in my life it was actually light in my kitchen while I'm making it so I can take photographs.
You don't have to add honey, using oranges instead of/as well as lemons also works. I tend to just use whatever citrus I have in. Make sure when you are taking photos of you putting the honey in that you are not looking through your camera at the jar because honey will go everywhere except into the jar. Its a bit sticky in my kitchen just now.
Put lid on jar. Shake jar until honey and liquid merge. Put in the fridge. Presto. Pretty much the easiest thing I've ever made and means no waste from barley cooking. Genius. I keep mine in a jar so I can take it to work with me, where people often assume I am drinking a urine sample. Oh what japes!
