1. Blow up a small clear balloon and tie to seal. Dip a side of the balloon into a large bowl of tempered chocolate, covering about halfway up the side of the balloon. Rotate balloon and repeat dip two more times, to create a petal like pattern. Shake off excess chocolate from the bottom. Place upright or at an angle (the direction will determine the shape of the finished bowl) on a rimmed baking sheet lined with parchment paper. Repeat process for additional bowls. Refrigerate until set, 3 to 6 minutes.

2. To test whether the chocolate has set, squeeze the balloon. If the chocolate pulls away from the balloon, then it is set. To remove the bowl, pop the balloon with a quick poke of a knife. Discard balloon scraps. Fill bowl as desired. Bowls may be filled with chocolate mousse, ice cream, or whipped cream, and garnished with berries.
