First, peel and chop the mangoes. Set aside a few pieces for garnish and put the rest in a blender jar.

Add the yogurt, cardamom powder, ice cubes, and sugar to the blender. Blend everything together for 1 minute until smooth.

Pour the prepared lassi into glasses, garnish with the reserved mango pieces and sliced almonds and pistachios, and serve the mango lassi chilled.
