Combine all the ingredients in a large pot. Bring to a boil, cover the pot, and reduce the heat to low. Cook for 60 minutes and then uncover the pot and continue cooking for 20 minutes more.
Remove from heat and let cool. Take about half of the corn and place in the blender or food processor. Return it to the pot and mix well. Place in a non-reactive container or a clay pot for a stronger flavor.
Put in the fridge until completely cold. You can drink it immediately or let sit overnight for a more intense flavor.
