A Liquorice Ball is a layered shot with a formerly saucy name (Slippery Nipple). The combination of grenadine, sambuca and Irish cream goes down smoothly.
Add the drops of grenadine to a shot glass.
Layer the Sambuca on top of the grenadine.
You should be able to get the Sambuca to layer by slowly pouring down the side of the glass, or holding a bar spoon upside down just over the grenadine and raise slowly as the glass fills.
Layer the Irish cream on top of the Irish cream using the same method as floating the Sambuca.
