3 to 4 boxes of colored, flavored Jello (I went for blue, green, yellow and red)
2 packages of Knox unflavored gelatin
2 cups Greek yogurt, divided
2/3 cup vodka, divided
Mix 1 package of any flavor gelatin according to the package directions. Typically, that is one cup boiling water added to the gelatin. Let sit a minute before stirring for three minutes and then adding 1 cup cold water. Pour into a dish or glasses. I use an 8×8 glass casserole dish if I’m making squares or you can use around six to eight pretty glasses. Refrigerate until set, which gives you about 30 minutes before you can move on to the next layer.
Mix 1 envelope unflavored gelatin with 1/2 cup hot water and stir until dissolved. Add 1 cup Greek yogurt and an additional 1/2 cup hot water. If you want to include booze, add 1/3 cup vodka to the measuring cup and pour in enough hot water to bring it to 1/2 cup liquid. Stir well to make sure it is well combined. Cool slightly before pouring half (just enough to cover the gelatin and make a thin layer) of the yogurt mixture over the set gelatin and refrigerate until firm, about 30 minutes. Leave the remaining gelatin/yogurt on the counter until after the next color layer.
Repeat the first step with the next color. Continue, interspersing color layers with white layers until done (or you run out of space in your vessel). I did mine starting with blue, then green, then yellow, then red (reverse Roy G Biv). For the cubes, I started with a violet layer.
These are best made the night before to help the layers bond to each other.
