Sobao pasiego

Sobao pasiego, a popular sponge cake from Cantabria, is made from yeasted dough that is typically flavored with lemon zest and either anise liquor or rum. Originally, the cake was made from leftover bread dough, but near the end of the 19th century, it has been modified into its present-day form. The tradition of preparing it and the simplicity of ingredients used in the preparation helped sobao pasiego gain PGI status in 2004.
