Something to cool a hot sunny day:
Honey Lemon Lime
And that's just what it is - honey + lemon + lime.
First, you zest the citrus fruits.
(Skip this step if you don't like the citrus bits in your drink.
But the zest imparts a nice aroma to the drink.)
Then you squeeze the juice out of the fruits.
Add as much (or little) honey as you like.
Or, if you like, soda water for some zing!
Throw in some ice.
