Salty, tangy, funky, spicy. Chaat masala is a spice blend originating from the Indian subcontinent, and variations on it are often used to season savory snacks (known as chaat) from food carts and roadside stalls. Chaat masala is also frequently sprinkled over fruits like apples, papaya, mango, and plum, imparting that signature hard-to-put-your-finger-on flavor.
