Chocolate containing tiny gas bubbles

Aerated chocolate, also known as air chocolate, is a type of chocolate that intentionally contains gas, forming bubbles.

Biting into some aerated chocolates produces an audible crunch, a phenomenon understood to be a product of its structure and texture. On entering the mouth, they generate a "fragile mouth feel" and quickly melt when chewed.

These phenomenon stem from the greater surface area, and intensify the flavor.

Rowntree's initially promoted aerated chocolate as more digestible than solid chocolate, though this was objected to by rival chocolate manufacturer Cadbury. Further to these objections, Cadbury contested the validity of the patent itself.
