Cut mangoes, by first cutting along the pit on both sides. Then make cross-hatch incisions, trying not to cut through the skin. Then pop out the back side and with a knife, cut the individual mango pieces.
Now add the rest of your ingredients to the blender, which include: -mangoes -yogurt -milk -cardamom -sugar
Pour and serve cold. You can drink it as is, or garnish with crushed pistachios.
