Duff Goldman and Valerie Bertinelli are cooking up something unusual in the science lab ... it's the freaky flavor tarts challenge! Each of the seven young bakers must create a large tart featuring a freaky flavor like jalapeno, goat cheese, yuzu, pink peppercorn, anise, blue cheese or curry.

Dessert impostors come in all shapes and sizes, so Valerie Bertinelli and Duff Goldman challenge the five young bakers to make sweet dessert tacos that look like the real thing.
