Eight of America's top bakers gather to begin the first in a series of Skills and Master Challenges designed to put their baking brilliance to the test. In the Skills Challenge, the bakers are tasked with baking flawless mini-upside down cakes. In the Master Challenge, the bakers must create a double barrel or a three-tiered wedding cake for 50 people, using lemon as the featured flavor. Judges Marcela Valladolid and Jason Smith determine which baker is eliminated.
