I was reading some vegan recipes on an American site last night and the ingredients kept listing vegan sugar. I thought it was strange as I had assumed that sugar was vegan but was surprised to find that Bone char can be used in its production - to achieve the desired colour.

Perhaps this is well known and I am really behind the curve - but what else should I know about?
