According to this post from TheKitchn these edible cups are made from the vegan jello alternative, agar agar, and can apparently be flavored to accent your cocktail!
I will confess that I haven't used agar agar before but am a little hesitant as it reminds me of high school science class...
Not sure I can get on board with this gelatin creation... They do look awfully festive though!
What do you think, friends??
