This recipe has been inspired by my recent trip to Santorini where I tasted the most delicious Orange Syrup Cake (Portokalopita) from the most wonderful patisserie in Oia. I was very surprised to find that no flour was used and that dried and flaked filo pastry is the key ingredient. This is a fluffy and colourful sponge made with fresh oranges and drizzled in a fresh orange and cinnamon syrup. Delicious!!
