1Hold an ear of corn upright and slice off the corn kernels from the cob with a sharp knife. Be sure to scrap the juice from the corn cobs, this will add natural sugar and intensify the corn flavor!
2In a large saucepan, bring the corn kernels, water and sea salt to a boil. Simmer for 18-20 minutes or until the corn is very tender. Turn off the heat and set aside.
3In a blender or food processor, puree the corn in batches until you achieve a smooth consistency. If you want a smoother soup, pour each patch through a food mill, strainer, or sieve. This will help you get rid of any large pieces. You can also serve this rustic style and keep the chunks of corn.
4Thin soup to desired consistency for thickness of the soup with buttermilk. Chill for at least 2 hours. Garnish and serve with fresh chopped herbs.
5Notes: Sometimes I like to add a drop of hot sauce to spice things up. I like to use the Asian hot sauce Sriracha.
