Have you heard of salt-rising bread? Probably not, if you're neither a passionate bread baker, nor a resident of certain parts of the country – the southern and western portions of the Appalachians, western New York down into western Pennsylvania, and parts of Michigan. This traditional American bread remains popular in these regions, where it's often sold in bakeries. But if you're living in, say, Colorado, or Connecticut? You probably never heard of salt-rising bread.
