What is Dark Chocolate (70% cocoa)?

Dark chocolate (70% cocoa) is made from cocoa solids and cocoa butter with sugar, with cocoa making up 70% of the bar. Compared with milk chocolate, it tends to be less sweet and has a deeper, more pronounced cocoa flavour. Chocolate has roots in the Americas, while cacao is now grown in several tropical regions.

The bar snaps cleanly and melts slowly, with a dense texture and a pleasantly bitter, roasted edge. It is eaten in small pieces on its own, alongside coffee or tea, or chopped into baking and desserts. It is energy-dense and contains fat, but also provides fibre; a modest piece can be satisfying. Try it with berries, orange, or nuts, or grate a little over porridge for a richer finish.
