In a saucepan combine the Kool-Aid, sugar, water, vodka, and agar agar. Give it a stir to combine and then place over medium-high heat and bring to a boil. Reduce heat to simmer and cook for about 3 minutes until the agar is dissolved.
Remove from heat and allow to cool slightly. Pour the cherry mixture into shot glasses. Place in the fridge to set, at least 30 minutes, but up to an hour.
Serve as-is or add dollops of coconut whipped cream and a maraschino cherry, and get ready for the fun!
Notes
Agar-Agar: You can use 1 tablespoon of agar flakes or 1 teaspoon of agar powder.I highly recommend reusable glass shot glasses rather than disposable plastic ones. They're not that expensive, and you can use them time and time again.
