I incidentally poured tea into a cup which still contained a small amount of coffee. I thought about wasting the mixed drink, but then I was curios what it would taste like. It wasn’t that bad, really. It tasted like, well, coffee and tea. I later wondered if there was this kind of beverage out there, so I browsed the internet and found out there were plenty of similar drinks.
One of them was a Chinese drink yuanyang, which is mixture of coffee and milk tea. I should have put milk into my accidental beverage.. too bad I only realized it now.
