Sponge toffee (also known as honeycomb, or as hokey pokey in New Zealand) is a sugary confection with a light, rigid, foam-like texture (described by one candy aficionado as "vintage foam rubber"). Its main ingredients are typically brown sugar, corn syrup, and baking soda. Sponge toffee is often sold in candy stores in small blocks, or covered in chocolate (most popularly as the Cadbury Crunchie bar.)
