Squid Mixes: Grape Crush

A grape crush combines vodka, Chambord and lemon-lime soda (I used Sprite) in a shot glass.  You slam the glass on the counter, then drink it down before it fizzes over.  I got my recipe from The Architecture of the Shot by Paul Knorr.  Despite having no grapey ingredients, it is supposed to look and taste like grape soda.  We both agreed that it did.
