Today the cultural tradition is celebrated on March 19, St. Joseph's feast day. Some church parishes in South Louisiana set up an altar for personal petitions that were granted. It is a lot of preparation beforehand by hundreds of volunteers. More information about how New Orleans carries out the tradition can be found here.
Below are pictures of one St. Joseph altar, a miniature altar and a plate of Italian cookies.
As my DH and I were walking out with our bag of cookies, fava beans and bread a lady said she saves a piece of bread to throw in her back yard when a hurricane is approaching to protect her property. I never heard that before but it can't hurt so we are saving a piece of bread just in case.
