This is a really good, really cheap gluten free corn flour. You can't use it to make polenta--that's corn meal, not corn flour. However, you can make skillet corn bread with this (put masa harina corn bread into Google, and it will pull up a couple of recipes--they also call for wheat flour, so substitute northern bean or white rice flour and a tsp of guar gum per cup of flour.)
If you're new to cooking gluten-free, watch out for cross-contaminated brands. This one is safe, because corn is the only thing they mill. It also says, "Gluten free" on the package. And, best of all, it's about a dollar a pound. (Brown rice flour costs twice that much.)Get more detail about Maseca Corn Masa for Tamales, 4.4 pounds.
