Also known as Brioche de Saint-Genix, this bread is always made round, “like the breast of St. Agatha.” That was quite a description for this non-Catholic. More investigation was necessary. 

Agatha’s breasts were removed with pincers as a punishment for not working hard enough at a brothel, which was a punishment for denying an unwanted sexual advance. She is one of the most venerated saints, often associated with breast cancer. The bread is made with Parisian rose pralines, a heavily-sugared delicacy that bleeds when heated. My first attempt was only semi-delicious. Perhaps the left breast will be tastier.
