From "Great Vegetarian Dishes" by Korma dasa:
Lassi (Serves 1)
1 c. plain yogurt ( I use fatfree I make myself)
1/4 c. cold water
3 ice cubes
2 tsp. sugar
1/4 tsp rose water (or more if you want- it's pretty potent)
Mix together in a blender until ice cubes are almost gone.
Top with finely chopped pistachio nuts.
You can add any kind of fruit for variety, but it tastes fine as is.
I find this absolutely light and delicious. I've also noticed that it
clear up yeast infections -- at least for me.
