There is an interesting article in today's Guardian on copyright.
Apparently the Italians are attempting to preserve the authenticity of their famous Christmas dessert bread panettone by "copyrighting" the recipe.
Manufacturers in other countries who change the ingredients or do not follow the traditional methods of baking will have to call their products by different names such as "sweet festive bread" or "sweet Christmas cake".
The authorities hope that regulating the use of the word panettone will safeguard the identity of a delicacy created in the Renaissance era.
This is part of a trend towards "copyrighting" Italian food.
