Had this at a cafe in Kyoto, seems home made as the ingredients were fresh, not even dried: sakura flowers and yuzu rind. The sakura flower, as the waiter explained, had salt on it, perhaps to help preserve it. Indeed the tea tasted like it had a bit of salty flavor, but the gentle sakura taste and yuzu rind taste where still predominant. It was a pleasant and adventurous experience but I would probably not order it again, due to the salt component.
