OK, I'm game, although this is a tricky one...
a) If you feel that 'proper' chocolate should have cocoa solids in it, i.e. cocoa beans, then white chocolate cannot be chocolate because it only contains cocoa butter.
b) If you feel that anything made using a cocoa pod is chocolate, then white chocolate is, indeed, chocolate.
So, it really depends where you stand. Personally, I get a bit confused! One minute I think a) is right, but then I think that b) has also got some promise.
What do you think? Oh, and you're right, Rainbow, this should be a debate, not an argument
