Recipe Instructions:
6 ears corn, shucked
6 cups whole organic dairy milk, plus more as needed
6 ounces shelled, roasted pistachios, plus more roughly chopped for garnish (optional)
1 small yellow onion, diced
Kosher salt and freshly ground black pepper, to taste
2 tablespoons minced chives, for garnish (optional)
Cut the kernels off the cobs into a large saucepan; using the edge of your knife, scrape the liquid and pulp from the cobs into the pan. Break 3 of the cobs in half and add them to the pan with the kernels.
Add the milk, pistachios, onion, 1 teaspoon of salt, and 1/4 teaspoon of pepper. Bring to a simmer over medium heat, keeping an eye on the pan to make sure the milk doesn’t boil over, and cook until the pistachios are tender and the milk is reduced to just below the level of the corn mixture, 45 to 50 minutes. Remove from the heat and discard the 6 pieces of cob. Let cool 30 minutes or to room temperature.
Working in batches, purée the soup until smooth. Strain through a fine mesh sieve, pressing on and discarding the solids.
Season soup with salt and pepper to taste. Transfer to a storage container and refrigerate until chilled, at least 4 hours or overnight. Stir well and thin with additional milk to your desired consistency, if needed. Ladle soup into individual bowls and garnish with chives and extra pistachios if you like.
