The final four chefs cook impromptu dishes while simultaneously instructing mystery partners on how to create the same dish; when the judges compare dishes, the chefs are shocked to discover their secret partners are their visiting family members.

The three remaining chefs head to the Yucatan Peninsula where Chef Roberto Muñoz Zurita challenges them to make a dish showcasing the flavor, complexity and heat of the legendary local habanero using ingredients from the local market. Culinary legend Jeremiah Tower gives the chefs a lesson on traditional Mayan cooking, before challenging them to create a dish using only ancient Maya ingredients and tools. The chefs will cook in an ancient cenote, or sinkhole, for a table of judges including local chefs Roberto Solis, Guillermo Beristain and Carlo Cardenas. The two chefs with the best dishes will move on to compete in the finale.
