Query: Very convenient, but lacking authenticity

The tortilla press is really great to have and the quality is quite good. The only bummer is that our whole wheat tortillas seem to be lacking that blistered effect,and they are a little more "spongy"... almost like the press needs to get hotter! We will keep it and use it often, but I am sure we will resort to our cast iron cooking technique when we want a more authentic effect.
