There is a shot known in Peru as the “Pelican Swallows the Pigeon”, and I think it only exists because it uses the leftovers from making a Pisco sour, and to fuck with people who lose pool matches and stuff like that. 

In a shot glass, combine:

• One egg yoke
• One part coffee liquer
• One part grenadine

That’s it.  It’s not good, but not that bad either.
