To a large bowl, add 1 cup fresh mango pulp. I got the pulp from 2 large sweet mangoes which I blended in a blender to make it smooth .
You can use canned mango pulp if you can't find sweet mangoes.
To the same bowl, now add yogurt. I have used plain whole milk yogurt here.
Now add cold milk (or water). I add this to thin out the lassi a bit. Also add the sugar and the cardamom powder.
Blend everything until well combined. I used an immersion blender.
Pour the mango lassi into serving glasses and chill before serving! You may garnish with pistachios, saffron strands before serving!
