If you are interested in recipes or information related to Puerto Rican food, here's a site for you: www.sazonboricua.com.
I just visited Sazon Boricua for the first time today. Boricua Jeannette Quiñones (aka fruttadi on flickr.com and a member of the Puerto Rico Sun photo group) runs Sazon Boricua. Her current entry features Puerto Rican-style sofrito.
I am adding a link to the site in this blog as well. Apoya lo nuestro.
