I’ve posted about tea before, but I was reminded of a tea that does not come from tea leaves. Roasted barley tea can be prepared hot or cold. I remember drinking it during the summers as a way to cool off. I can also get it at a Korean restaurant as a hot tea.
Chinese: 麥茶 (mai cha); 茶 is the word for tea
Japanese: 麦茶; むぎ ちゃ (mugi cha)
Korean: 보리차 (bo ri cha)
