Sandy Lee made the following cocktail on her Semi-Homemade programme:
Vodka
Lemonade
Heavy Cream (!!!)
Somebody slowed down video of her drinking this and her wince is a startling poker-tell. (The animated gif above will save you the trouble of clicking through to the video.)
I haven't tried it myself but Sandra's infamous for some dangerously questionable concoctions. Caveat emptor.
