There are convents all across the caminos that create and sell baked goodies. Some of them use "turns" so you can't see who's inside; others are more open, in a shop setting. I know the Clarisas in Castrojeriz bake amazing "twinkie" kinds of cakes. The Benedictinas in Sahagun bake fabulous almond cookies. Lots of these have wonderful names: "Bones of San Lorenzo," "Sighs of the Novices," etc. In Santiago de Compostela there was a shop near Ivar's office that sells all kinds of home-made monastic goods -- cakes and cookies, preserves, honey, tapenades, olives, as well as rosaries and altar cloths.
