The Hot Cinnamon Spice tea from Harney & Sons is so sweet that I mistakenly thought sugar was added to my morning pot of tea. It's a bold, bright black tea tangled with cracked cloves and orange peels. It shouldn't come as a surprise that this is Harney & Sons's single most popular flavored tea, boasting three types of cinnamon to deliver a simultaneously spicy and sweet drink. Just a splash of milk and nothing else—the natural sweetness is plenty satisfying. Twenty sachets to a tin, $8 at Harney & Sons.
