Create simple Jell-O shots by adding boiling water to a package of gelatin and mixing in alcoholic spirits. About.com recommends pouring the hot liquid into plastic shot cups that are easy to squeeze to allow the gelatin to set.
The recipe available at About.com recommends using 3 ounces of any flavor of Jell-O or another brand of gelatin and 1 cup of boiling water. Those mixing the shots may wish to add an equal amount of water and vodka, or other distilled spirits, to water down the flavor of the alcohol. About.com suggests using 1/2 cup of liquor and ½ cup of water for this purpose. Bartenders or hosts may also add food coloring to change the look of the Jell-O shots, as desired.
DrinksMixer.com notes that any variety of Jell-O flavors and spirits is likely to work well, and the simple recipe offered by the website uses 1 cup of coconut rum, 1 cup of boiling water and a 3-ounce package of gelatin powder. As with the About.com recipe, hosts should mix the boiling water and gelatin first and add the spirits before the gelatin has time to cool. DrinksMixer.com suggests pouring the hot result into 2-ounce shot glasses for service.
