Chai is a rich blend of black tea, spices, milk, and a touch of sweetness. Tea flavored with a spice blends that stretch back 5,000 years to Ayurvedic medicine. Chai was made a staple in the 1840s by chaiwallahs (tea street vendors) selling cups served in earthenware vessels, a tradition that is still seen today. While the spices may differ by family and community, the warmth and comfort they offer is truly universal.
