The challenge
Many people assume gluten-free food tastes like cardboard.
The idea
Wholegreen Bakery and The Hallway took the common insult literally and baked a cake that mimics a cardboard box. Accredited by Coeliac Australia, it invited doubters to try it and admit they were wrong about gluten-free baking.
