This dessert is believed to date back to pagan times, when Neapolitans would offer all the fruits of their land to the mermaid, Partenope, in Spring; eggs for fertility, wheat from the land, ricotta from the shepherds, the aroma of orange flowers, vanilla to symbolise faraway lands and sugar in honour of the sweet mermaid. It is said the mermaid would take back all these ingredients, immerse herself in the sea of the Bay of Naples and give back to the Neapolitans a dessert which symbolised fertility and rebirth! It has always been traditional to make this tart at Easter in the Campania region of Italy and Easter just wouldn't be the same without this dessert ! Pre-cooked wheat is sold in all good Italian delis and orange-flower water is found in good supermarkets.
