I was ill with a horrible cough the other week, and made lovely soothing drinks with oranges, lemons and honey. It was so much yummier than your regular old lemon & honey that your mum used to make when you had tonsilitis.
Then my sore throat went away, and the sun came out (very briefly) and I still wanted to drink this yummy drink.. so I made a chilled version and added echinacea to keep any more colds at bay!
It's really easy, you just need a big jar/bottle/something to put it in, and mix all the ingredients to your taste. Chill it for a bit, and then drink it down! YUM!
