Strawberry Vodka
If you've got anything pressing to do the next day, then a ratio of three parts juice to one part vodka is also good.
But come on - live a little...
one part strawberry & orange juice *
one part vodka
The main thing here is: you have to keep your vodka in the freezer. It improves it no end, making it thicker and a little syrupy (no, it doesn't freeze).
Then you mix it with some juice, serve to pals, and all sit back and watch the sun set.
* M&S do a good one.
Del Monte's Orange, Apricot and Peach juice is also very good with vodka.
