Yuzu makes a great tea, I drank lots of it while abroad in South Korea during the winter. It's equal parts sugar or honey and sliced up fruit peels into a jar, will last a few weeks in the fridge. I made some with meyer lemons but it's not the same. Really opens up the sinuses and the vitamin C is great. If you'd like to try it, Asian grocery stores such as Hmart, Mitsuwa, etc carry it. I've seen some at Costco once
