I think I am only all the more confused.
What am I supposed to buy for my cooking?

cornstarch is probably easier to find - it should be in the baking aisle

cornstarch is much easier to find. Like Mama said, it's in the baking aisle. It's what you would use for thickening gravies and whatnot.

cornmeal is the yellow ground corn product and is usually next to the flour. it's used to make cornbreads.

cornbread....hmmm....guess what might be for lunch today.

okay, I bought both at the store yesterday.
Will check with you guys before I use them in anything..lol!
I don't want to end up with something disastrous.

Great! that you could find both of them. So I am sure and so are you, that they aren't one & the same thing!! :p
