Semolina is generally made from wheat it is not in general made from cornmeal.

Despite it's unfortunate name ("Cali" plus camel case—double oof!), the CaliBurger looks freakin' great. A great burger walks a very fine line. So many try too hard, tipping the burger from it's backyard or cast iron roots into some gross, inedible rich meatloaf sandwich.

@1 - a bun that contains cornmeal can be primarily made of semolina. The two aren't mutually exclusive.

@1 Of course, if the bun is made with semolina MEAL (instead of semolina flour) it would be super easy to confuse the texture of that for corn meal. :) I withdraw my comment.
