A special cake made for Ag. Fanourios on the saint's feast day, August 27. Made without dairy or eggs (hence nistisimo), it's made with orange juice, flour, vegetable oil, raisins, sugar, cinnamon and cloves. It should have seven or nine ingredients, as per the seven days of Creation or the nine Mysteries of the Orthodox Church. After it's baked, the fanouropita is traditionally be cut in 40 pieces (for the 40 days that Christ spent on earth after the Crucifixion) and shared among seven people.
St Fanourios's name comes from the Greek word for revelation, φανέρωση (fanerosi), and like St Anthony in the Catholic church is famous for helping people find lost items or people; baking a fanouropita or 'lost and found' cake is supposed to encourage him to help a little more.
