Madeleines

The madeleine or petite madeleine ([pə.tit mad.lɛn]) is a traditional small cake from Commercy and Liverdun, two communes of the Lorraine region in northeastern France. Madeleines are very small sponge cakes with a distinctive shell-like shape acquired from being baked in pans with shell-shaped depressions. Madeleine-style cookies are popular in a number of culinary traditions.
