Try out a lassi. This is Indian version of a smoothie. You can make sweet or spicy versions with salt and spices. Believe me both are simply amazing. Dry roast about one tsp cumin, powder it and keep it aside. Take a few leaves of mint and your favorite plain yoghurt, add ice cubes or cold water, some of the cumin powder and salt. Give it a whirl in your blender and sprinkle the powdered cumin on top. Enjoy ice cold lassi. Make a sweet version with mango and thick plain yoghurt and ice cold water. Add a little sugar if you like it really sweet. Nothing better than a mango lassi on a hot summer day.
