Lassi is a yogurt based drink popular in India and can be made in different flavors. If you haven't tried this yet, this is a must try - you sure would come back for more.
2 cups ripe mangoes, peeled and sliced or 2 cups sweetened kesar mango pulp (you can get tinned ones at the Indian grocery stores)
1and 1/2 cups plain yogurt
1/2 cup milk
4 tablespoons sugar or to taste(adding sugar is not neccessary if you are using mango pulp)
Blend all the ingredients together in a blender to a smooth puree. Serve with a dollop of vanilla icecream if its extremely hot or have it as it is.
It is best if all the ingredients are pre-cooled, rather than adding ice cubes while blending it. Adding ice cubes would dilute the lassi and though many use this method, I prefer the thicker consistency. If I need it colder, I would just add some ice-cream on top.
