1. 3/4 fill a pint glass with cold water
2. add ice to this till its near the top of the glass
3. add a teaspoon of sunshine orange or st clements you might want to start with half a teaspoon first.
4 stick in the blender till the ice is crushed up a bit - then stop the blender whilst you add a vanilla pack - otherwise you'll be mopping it up!
5 put the blender back on and blend for a few minutes..
6 enjoy
the amounts I told you makes a pint and a half...you may want to make it with less water for a stronger taste.
I got this one from Icemoose!
