To make Jell-O shooters with vodka, mix one cup of boiling water with a package of flavored Jell-O. Mix until the Jell-O has fully dissolved, and add one cup of vodka. Pour the mixture into shot glasses and refrigerate the shooters for at least four hours before serving.
You can make almost any cocktail into a Jell-O shooter, or use combinations of Jell-O flavors to create new shooter cocktails. The trick to making any cocktail into a Jell-O shooter is to maintain the cocktail's original proportions, keeping around 1 cup of liquid volume total.
To make rainbow Jell-O shooters with vodka, get a package each of red, orange, yellow, green and blue Jell-O. Use separate bowls to dissolve each Jell-O flavor in boiling water. Add one layer at a time, allowing around 10 minutes between layers for the Jell-O to set. Layer the flavors by color into shot glasses, and chill in the refrigerator for at least four hours. Slice colorful fruits to garnish the shooters.
You can use other liquors to make cocktail favorites into Jell-O shooters. For instance, to make margarita Jell-O shooters, mix lime Jell-O, 1 ounce of triple sec and one cup of boiling water. Add 1/4 cup of tequila, and chill the shooters in the refrigerator. Rim the shot glasses with salt before serving, and garnish with a lime.
