I cooked pasta for a chef once. He tasted it - glared at me because I hadn’t put salt in - and tossed it all in the bin! Lesson learned… yeah, learn not to cook for arseholes. If he’d wanted salt he could have added it at the table. Twat.
For the people saying that food has to be seasoned during the cooking process, garlic, ginger, various other herbs are excellent substitutes and contain far more flavour than salt.
Equally salt is an acquired taste, so some people prefer more salt than others, in which case they can season their food at the table.
Most foods contain some salt, even dried pasta and tomato purée for instance contains some salt. but either way, not cooking with salt doesn’t mean never adding butter, or cheese or stock, it means not actually grinding salt into a saucepan which is to your taste rather than the taste of everyone you’re cooking for.
We should eat no more than 6g of salt a day. You’d be surprised at how quickly you arrive at that number.
