The French Brittany is famous for its interesting dishes and the famous Breton cakes three. Far breton — cake of batter, often with prunes, to some extent, even more a dessert than cake, similar in structure to the puddings. Kouign-Amann — oil-yeast pie with delicate puff pastry. And the gâteau breton Gateau Breton, according to legend, was intended primarily for sailors who went for months at sea. This pie had the amazing preservation properties, so the sailors could enjoy it for several weeks or even months after their departure. Thus, they felt the taste of his homeland. For the preparation of a Breton cake was usually used salted butter, I was very interested to try, but the store I then salted butter is not found. But, to my amazement, was able to buy it at the agricultural fair, local producers. Don't know how much has to be salted butter in the original, but mine was very slightly salty, so I'm not even worried about the result.
