With Halloween just around the corner, this has to be best Halloween ‘Themed’ Drinks idea for the budding mad scientist to create, simply add chilled Vodka and Lime juice to a shot glass, then use a straw or small tea-spoon to drip Irish cream into the mix. The acidity from the lime juice will cause the Irish cream to curdle, creating realistic blobs of ‘brain’ and for that extra ‘gore’ just add a few drops of blood-red grenadine into the drinks and abracadabra you have Halloween Blood Brain Vodka Shots.
