Any chocolate will do in an emergency, but getting your day started is all about administering the cacao drug. The stronger your chocolate,
- the less you need to satisfy the craving (in theory anyway)
- the less sugar, milk fats and other gunk you are starting the day with
- the bigger the grin
The kick from dark chocolate is not caffeine - much. You need about a kilo (over two pounds) of good dark 70% choc to equal an espresso (unless of course it is chocolate with coffee in it: Whittaker's Dark Moccha just about blows my head off).
