Multiple sources attribute this to Qing Dynasty Emperor Qianlong, though I haven’t located the original source:
Set an old three-legged teapot over a slow fire.
Fill it with water of melted snow.
Boil it just as long as is necessary to turn fish white, or lobsters red.
Pour it on the leaves of choice in a cup of youe.
Let it remain till the vapor subsides into a thin mist, floating on the surface.
Drink this precious liquor at your leisure,
And thus drive away the five causes of sorrow.
