This much lighter festive bread is a very interesting variety of the traditional raisin bread (stafidopsomo). This version comes from Mykonos, and was given to me by Anna Sigala, my neighborhood baker. She got it from her grandmother.
My mother and father hated raisin bread because, for a period during the 1930s, the Greek government made it compulsory for everyone buying any kind of bread to buy some raisin bread, too. The Ministry of Agriculture had bought all the raisins from Corinth to keep the growers satisfied, for political reasons, and then invented this method to get rid of the surplus.
Later on, when this stupid regulation was no longer applied, raisin breads disappeared from the bakeries because no one would buy them. Only recently, more than two generations later, is raisin bread again becoming popular.
