Sherrard's Hot Ginger Apple Juice
If you have a cold but you're soldiering on (or even if you're not) this is very good:
1 4-liter jug of fresh, unfiltered apple juice
some sliced fresh ginger
4 or 5 cinnamon sticks (you can use ground if you don't have the sticks)
glug glug glug of lemon juice
Heat this up almost to boiling in a big pot or kettle and let it brew for an hour. You can drink it through the day off the top of the stove, or pack it to work in a thermos, or refrigerate it and heat cups in the micro. It might not cure your cold, but you will feel warm and zippy.
Question: who hasn't got a cold right now?
