Lei cha

Lei cha (Chinese: 擂茶; pinyin: léi chá; lit. 'pounded tea'; pronounced [lěɪ ʈʂʰǎ]) or ground tea is a traditional Southern Chinese tea-based beverage or gruel that forms a part of Hakka cuisine. In English, the dish is sometimes called thunder tea since "thunder" (雷; léi) is homonymous with "pounded" (擂; léi).
