black or white chocolates?

I agree with your mother, they do taste different. I prefer milk chocolate to white chocolate. Not that they both aren't very good, I just prefer the milk chocolate. It has just a little better taste for me.

i like dark chocolates, it's so good! i like them more than milk or other chocolate, maybe because other chocolate have the same taste, but dark chocolate has a unique taste!

Your mother is correct, at least that has been my experienced. White has more texture and is far more sweeter. Other/brown/dark/chocolates are not as sweet and are very lite, more milky for lack of a better word. White does not in the same manner white does....white is better to me and I don't care for any other type of choc.

I think chocolates are of 3 types: white, milk and dark. You may have tried white and milk so the difference isn't so profound. white chocolates are sweeter. There is less cocoa taste. I prefer dark chocolates. Those are really concentrated. I suggest you try it again. Eat a white one than a dark one (not milk chocolate)
