Puchka, also known as golgappa or panipuri, is a popular street food snack in Kolkata. It consists of crispy hollow puris filled with a mixture of spicy and tangy flavored water, mashed potatoes, chickpeas, and tamarind chutney. The puris are usually made with semolina or wheat flour and are deep-fried until they become crispy. Puchka is a favorite among locals and tourists alike, as it offers a burst of flavors and textures in every bite.
