After the Battle for the Apron concludes, the Top 22 home cooks in America will face their first Mystery Box Challenge. Each contestant is given 20 staple ingredients that anyone could find in their home and tasked with preparing a dish for the judges -- were the judges to show up at their homes for dinner. The winner of the Mystery Box Challenge will receive a significant advantage in the season's first pressure test, during which contestants must make their versions of an apple pie.
