Lemon and Mint drink
There's a lovely middle-eastern recipe for mint lemonade.
I used to make loads of this stuff in my navy days.
So, for a jug serving six sailors:


Juice of about 2-3 lemons
Six tablespoons of sugar
nice handful of mint


Put the mint and sugar in the jug and pour about half a cup of boiling water. 
Stir well, and leave for a few minutes so that the mint can think about what it has done.
Add lemon juice and water slowly while stirring.

The amounts may not be precise, as I used to make this in an eight gallon saucepan, and these days I make it in a 2-cup shaker.
