Barley tea is supremely refreshing alongside Korean bibimbap or Japanese sushi. And you can make your own at home. Buy bags of roasted barley (or, alternatively, a mixture of roasted corn and barley) at an Asian market, and boil it on the stovetop until the roasty flavors infuse the water. (Just steeping it in boiled water will not release the flavor.) If you’re the DIY type, you can roast barley yourself–just toast it in a shallow pan on the stove, and don’t forget to stir, says Kater.
