Ingredients
36 plastic shot glasses
2 3-oz. boxes berry blue Jell-O
3 envelopes Knox plain gelatin, divided
2 1/2 c. cold vodka, divided
1/2 c. milk
1/8 c. granulated sugar
Preparation
Step 1Before starting, line up all shot glasses on one or two cookie sheets that will fit nicely in your fridge. Step 2For first blue layer: In a medium saucepan, mix together 1 cup water with one box blue Jell-O and sprinkle 1 envelope gelatin on top. Allow mixture to sit for 1 minute, then whisk everything together; heat on medium until it reaches a simmer. Add 1 cup vodka and whisk together again. Place 1 tablespoon of blue Jell-O mixture into each plastic shot glass and place in fridge for about 30 minutes.Step 3For white layer: In a medium saucepan, sprinkle 1 envelope gelatin over milk and allow mixture to sit for 1 minute. Add sugar and whisk everything together; heat on medium until it reaches a simmer. Add 1/2 cup vodka and whisk again. Wait for white gelatin mixture to cool down to room temperature before layering (it can cause colors to melt and bleed otherwise), then add about 3 teaspoons white mixture to each shot glass. Refrigerate for another 30 minutes. Step 4For second blue layer: In a medium saucepan, mix together 1 cup water with blue Jello box and sprinkle 1 envelope gelatin on top. Allow mixture to sit for 1 minute, then whisk everything together; heat on medium heat until it reaches a simmer. Add 1 cup vodka and whisk together again. Allow mixture to cool down to room temperature, then top off each shot glass with about 1 tablespoon plus 2 teaspoons blue Jell-O. Refrigerate again for at least 3 hours before serving so Jell-O shots are completely set.
