Hominy is made from dried corn which has been treated with CAL (calcium hydroxide). In Mexico this is called pozole, Native Americans call it hominy. Once the corn has been treated it can either be cooked or re-dried for future use.
You can make your own hominy by cooking large kernel corn with cal. The cooked hominy has to be rinsed very well and have the kernel heads picked off. Or, you can purchase pozole which is already treated with lime, cleaned, then re-dried. See complete instructions for making hominy here.
If you don't have hominy then consider some of these options.
