They are essentially Jello in shot glass. The jello however, is made with vodka, tequila, whatever alcoholic shot of your choosing.
It is a fruit-flavored gelatin dessert made from a commercially prepared powder. Basically it's like squishy cubes or whatever you cut it into. Tastes like the fruit it's supposed to emulate. Has a smooth and jiggly movement. Think of a giant gummy bear, just not as chewy because its soft and breaks easily.
Oh, is it? *takes the jello* *quietly stares at this foreign object...* A Giant Gummy bear? What does that taste like? Are you the killer?
