Also find it funny that PP thinks having to use salt makes you a shit cook. I guess all the professional chefs out there are shit cooks too
The reason restaurant dishes taste great is because chefs layer salt across every part of their cooking to bring out each individual ingredients flavours, use fat and oil liberally, and balance flavours with acid and sometimes a small bit of sugar/sweetness. A "fantastic" spaghetti bolognese from your local Italian would be cooked in generous amounts of olive oil, with a bit of salt added to the onions while cooking, and also to the mince, and then also to the tomatoes (which is the acidic aspect of the dish). A bit of sugar would be added to balance the acidity of the tomatoes, either as a pinch of white sugar or as grated carrot for example
Sweet baked goods taste far better with a pinch of salt added as it balances the sweetness and makes it less likely that you'll end up with a sickly sweet dish. Most sweet recipes call for 1/4 or 1/2 a teaspoon of salt in the entire mixture (eg an average cake recipe), which is really a tiny amount of salt in the grand scheme of all the other ingredients!
Many people who say they don't cook with salt actually do cook with salt because they inadvertently introduce it through other means, eg they'll say "I never cook with salt, can't stand it!!" But then throw in half pack of bacon to the dish instead
Unless you have a health condition, there really is no reason to restrict salt beyond normal, sensible levels. Chugging and entire jar of salty anchovies daily isn't good for anyone, but unless you've got kidney issues or high BP, a bit of salt in your cooking really isn't a big deal. Salt being evil, the devil, will kill you etc is hyperbole. The same way fat free yoghurt only tastes good because its got a shit load of sugar in it, when in reality it'd be healthier to simply have the fat in the yoghurt in the first place than adding refined sugar to make it palatable
