  • 1 teaspoon vegetable oil
  • 1/2 yellow onion, finely chopped (about 1 cup)
  • 1/2 poblano chile, seeded and finely chopped (about 1/2 cup)
  • 1 large garlic clove, minced
  • 1 teaspoon ground coriander
  • 1/2 teaspoon ground cumin
  • 1/8 teaspoon ground turmeric
  • 2 1/4 cups corn kernels (about 4 ears)
  • 3 cups nonfat buttermilk
  • 3/4 teaspoon coarse salt


  1. Heat oil in a medium saucepan over medium heat. Add onion, poblano chile, and garlic; saute until onion is soft and translucent and chile and garlic are tender and fragrant, about 5 minutes.

  2. Add coriander, cumin, and turmeric, and cook until they are toasted and fragrant, about 2 minutes. Add corn, and saute until kernels are lightly browned, about 5 minutes. Remove from heat, and let cool slightly.

  3. Transfer 1 1/2 cups corn mixture to the bowl of a food processor fitted with the metal blade, and add buttermilk and salt; puree until mixture is smooth. Transfer to a large bowl or plastic storage container; stir in remaining corn mixture. Cover with plastic wrap, and place in refrigerator until soup is well chilled, at least 2 to 3 hours. Remove from refrigerator; ladle into bowls, and serve.

Cook's Notes

This soup can be made up to one day ahead and stored, covered, in the refrigerator; stir it again before serving, as it may separate while it sits.
