Dried and true! In this third Alton’s Challenge battle, there’s a dehydration theme for the baskets and Alton demonstrates a home hack that makes removing moisture from food a breeze. The first basket has the chefs making quick use of instant mashed potatoes. Then, an Alton specialty is one of the mandatory ingredients for the entrée round. In the dessert basket, diabolical ingredients have the chefs scrambling to make dehydrated eggs work in their final plates.
