The only thing I add salt to at the table is chips or eggs. D's SO who has been living with us for a few weeks now, adds salt and pepper to almost everything I cook before he's even tasted it spag bol last night and turkey stew tonight for instance. He bought himself a salt and pepper grinder as I only keep table salt and ground white pepper.
If it's not to his taste fine, but at least try it first !
Static caravan purchase is it worth buying
