This classic Indian drink, called a "lassi," is made with yogurt and provides a cool foil to curries, including our Shrimp Masala. This version gets its richness from pistachios and a hint of spice from fresh ginger.
Blend yogurt, water, ginger, salted pistachios, pepper, and ice cubes until smooth. Divide among glasses. Garnish with finely chopped pistachios.
