I love lassi. Here is how you make a decent one.

Crush up 2 cubes of ice + 1/2 cup yogurt + 1/2 cup ice water + 1 teaspoon sugar  + tiny pinch salt + a few drops of rosewater + fresh mint leaf in the blender.

Some people like cardamom or cumin and some like half a mango or a handful of fruit added in.

This one has some green melon in it. It's not bad. Mango, blueberries or strawberries is better. Plain is best. This is a good recipe for kids to make.
