First chill one martini glass.

Then, shake up 1 part limoncello (lemon liqueur), 1 squeezed lemon wedge and 1/2 sugar syrup. Pour into the martini glass.

Next, shake up 1 part galliano (vanilla liqueur) and 1 part half-and-half (milk an d cream) in a boston tin without ice. Layer this on top.

Finally garnish with something pretty, such as a lemon peal twirl.
