There is a long tradition of bakery products for Easter all over continental Europe—and even beyond, as the popularity of the hot cross bun in the UK and former British colonies like the US and Australia shows. In the more traditional regions, especially those in the Mediterranean area, it is often a form of plain flatbread or wafers that are a prominent part of the tradition. In Spain a whole wafer industry has developed for the Semana Santa, and in rural areas with stronger and older traditions these wafers and especially more traditional flatbreads are sold or handed out to the people attending the ceremonies of the Holy Week, especially on Good Friday and on Easter Sunday. (Please note that these products are all distinct from the liturgical communion wafers.) In Greece there is for example a long tradition of women baking the so-called koulouria using outdoor ovens (see image below).
