Mother in Laws Tongue

Recipe by Whitby Tart

This is a very very rich chocolate bar, Unfortunately once you have tasted this slice you can not leave it alone, It was given to me about 15 years ago by a friend. The reason for the name if the slice is because a mother in laws tongue is usually bitter sweet.

WOW! This was really easy & great tasting. I must admit I did not use dark chocolate, I used Milk Chocolate. The family LOVED it, maybe a little too much! I will definately make these again. Thank you.
