Not a pizza, in spite of its name, but a yeast-based cake made with ricotta and wine flavoured with anise, with tiny pieces of candied fruit and raisins, traditionally served on Easter morning around Rome.
Also known as pizza de Pasqua de Civitavecchia (which claims to have invented it) or pizza de Pasqua alla romana, pizza cresciuta or pizza ricresciuta. Traditionally it is baked a week before Easter to enhance the flavours.
