Here is some info I've gathered when I was looking for recipes a few years ago. Hope some of it helps you!
Practical Tips for Making Jello Shots
Never cook the alcohol or pour it into boiling water unless you want non-alcoholic jello shots.
Allow more time than usual for the Jello to set because of the alcohol in it.
Too much alcohol overpowers the shooter, making it unpalatable. A good rule of thumb is to use alcohol equal to half the water called for (all of the cold water).
Using plastic Jello shot cups with lids is the easiest means of storing and serving Jello shooters. The lids make for easy stacking in the refrigerator. To serve, simply place the containers on ice in a punch bowl.
To eat Jello shooters, run your finger or a popsicle stick around the edge of the shooter to loosen it and shlurp it down like an oyster on the half-shell. Please eat responsibly.
A lot of jello shot recipes call for '1 package' of Jello, without specifying the package size, but you can figure that out by the total amount of liquids in the recipe:
A small (3-ounce) box of Jello calls for a total of 2 cups of liquid.
A large (6-ounce) box calls for 4 cups of liquid.
The Basic Vodka Jello Shot Recipe
is an excellent way to learn how to make Jello shots. The principles are the same for every other shooter recipe:
1 (6-ounce) box of Jell-O, flavor of your choice
2 cups boiling water
2 cups vodka
In a bowl, pour the boiling water over the Jello and stir until thoroughly dissolved. Cool to room temperature, then stir in the vodka. Pour the mixture into shot glasses or Jello shot cups. Refrigerate until well-set, at least 6 hours. Makes 32 1-ounce jello shots, give or take.
