You might already be familiar with storing wheat and rice, but corn? What about storing some popcorn or corn meal? We use both at our house regularly. Popcorn kernels are easy to store like any other grain. Corn meal , like flour, must be rotated more regularly. But just like wheat can be ground into flour, corn can be ground into corn meal. All you need is a good grinder (watch for a future post on grinders!).
