make non-alcoholic -- Homemade Limoncello. An Italian woman I used to work with brought this to our Christmas party one year. It's like a shot of lemon meringue pie! So delicious and dangerous considering the alcohol.
The Marshmallow Shooter is a cocktail I came up with when I was trying to make a drink that tasted like a marshmallow. It's vanilla, sweet and just a little bit buttery. Not exactly marshmallow, but good.
