Step 1

Place 14 ounces frozen mango pulp or 14 ounces cold chopped mangoes, 2 1/2 cups cold whole-milk plain yogurt, and 1 pinch ground cardamom if using in a blender. Blend on high speed until smooth, about 1 minute.

Step 2

Taste and blend in powdered sugar a teaspoon at a time until desired sweetness. If the mango lassi is too thick (aim for the consistency of a smoothie), blend in 1/4 cup cold water. Pour into 3 or 4 glasses. Garnish with slivered or chopped pistachios, or a pinch of crushed saffron threads if desired.
