Mini Beer Mug Shot Glass
Why have a typical shot when you can have a mini beer shot. All you need is Licor 43, heavy whipping cream, and this mini beer mug shot glass (sold in a set of 6). The Licor 43 will go into the glass first to imitate the beer and followed by the heavy whipping cream to imitate the foam.
And if you want to have mini Guinness shot, add some coffee liqueur and followed by some Irish cream.
