If you're baking, salt is usually necessary on many levels. It brings
out the flavor of the butter or sugar or lemon or vanilla. And in
bread baking, it checks the growth of your yeast. Nothing more ghastly
than bread with no salt! Unless of course you must go without due to
health issues. If you're expecting others to eat your food, make two
batches. Saltless food just plain sucks. ;-)
