EXPERT VERDICT: ‘Fresh cocoa beans have a higher flavanol content than commercial chocolate, so a “raw”, or less processed, bar should be more nutritious. However, no research I know of has proved this is the case. Also, “raw” chocolate has no set definition so it could still have gone through substantial processing. It’s made from “raw cacao powder” but cacao is just another word for cocoa and doesn’t necessarily mean any extra health benefits.’

TASTE TEST: Very bitter, but surprisingly smooth. Slightly cloying aftertaste.
