This might sound silly but I miss sale grosso; kosher salt is similar but not the same.
Many people think that you can always use sale fino, regular table salt.
But this is not true.
Sale grosso is a crucial ingredient for focaccia salata or focaccina or schiacciata
You need to put a generous pugno (lit. ‘kick’) of sale grosso into boiling water before pasta.
and it is perfect for a scrub (anti-cellulite!)
