thumb|Tray of jello shots An alternative recipe calls for the addition of an alcoholic beverage to the mix, contributing approximately one third to one half of the liquid added after the gelatin has dissolved in a boil. A serving of the resulting mixture is called a "Jell-O shot", or the genericized "Jello shot", at parties. The quantity and timing of the addition of the liquor are vital aspects; it is not possible to make Jell-O shots with liquor alone, as the colloidal proteins in dry gelatin consist of chains which require a hot liquid to denature them before they can then reform as a semisolid colloidal suspension. Pure alcohol cannot be heated sufficiently to break down these proteins, as it evaporates.My Science Project – What is the Ultimate Jell-O Shot? .
