Prosforon ("Offering") is the altar bread used for communion, literally transformed into the body of Christ during the Eastern Orthodox Divine Liturgy. And it does not come from a bakery.
It is offered by a congregant who has baked 5 loaves stamped with a religious seal at home and brought them to church, usually with a list of family names (living and deceased) to be read during the service.
A few days ago, I was lucky to get a Prosforon-baking lesson. It took place in a home kitchen where my grandmother Eugenia Sarris had given my teacher that very same lesson. I am sure there is more than one kitchen in Stockton/Lodi/Tracy where that happened -- just like other women taught their daughters and friends over time, passing on a tradition of serving the church in this most meaningful way.
At St. Basil's, one congregant bakes the Prosfora for every Divine Liturgy during an entire month. Sometimes it's not so easy to line up 12 bakers for this important task, so new volunteers are always needed to keep up the baking tradition that has been so much a part of St. Basil's Church life for 84 years.
How about you? Baking lessons (if needed) will be provided. I can vouch for that!
