Corn Traditional Masa

I would like to preface this with I always like to do stuff the 'old way' traditional way.  :-)

I bought some corn to grind for corn bread and tortillas and then I found out that our bodies really don't break corn down well so we don't get all the needed vitamins from it.  How do we get the vitamins???  By soaking in lime.  So if you too have some corn and would like to make traditional torillas as well here is how.
