Buttermilk, packed with calcium and probiotics, lends a subtle tanginess to this spice-spiked lassi. Finish with a sprinkle of chopped pistachios for a hit of crunch.
In a blender, puree peaches, buttermilk, ice cubes, sugar, cardamom, cumin, salt and liqueur, if desired, until smooth and frothy. Add sugar to taste. Divide among 4 glasses and top with pistachios. Serve immediately.
