It's Biscuit Week and there's a trip Stateside for the bakers in the Signature as they make American-style cookies. In the Technical, it's a journey of a different kind as they travel back in time for a nostalgic classic. But nothing is quite as it seems and they must rely on their taste alone to recreate this beloved bake. And in the Showstopper, a visually striking biscuit mosaic tests the bakers' artistic flair and also gives them the chance to create something that's close to their hearts.
