Hi! Could you please explain why should we use unsalted butter in the Pizza Rustica then add salt? I don't usually cook with salt. Silly question is it absolutely necessary? Many thanks for reading this.
Nigella's Pizza Rustica (from Domestic Goddess and on the Nigella website) is not the type of pizza that we would traditionally think of, but an Italian pie filled with a mixture of cheeses and cured meats ("pizza" means "pie" in Italian). The crust ia made from a shortcrust style pastry.
The recipe specifies using unsalted butter and then adds salt as Nigella prefers to be able to control the level of salt to personal taste. With salted butter it can be difficult to know how much salt is being added. The salt is added as pastry can taste a little dull without salt, but by all means please do reduce the salt, or eliminate it completely, to suit your own personal taste and preference.
