Alton's Challenge, Part 2

In the second Alton's Challenge battle, there's a dehydration theme for the baskets, and Alton Brown demonstrates a home hack that makes removing moisture from food a breeze. The first round has the chefs making quick use of instant mashed potatoes, then an Alton specialty is one of the mandatory ingredients for the entree round. A diabolical dessert basket has the chefs scrambling to make dehydrated eggs work in their final plates.
