Recipe

1. Slice kernels off each ear of corn to yield 4 to 5 cups of kernels. Cut or break 2 cobs into 2″ to 3″ pieces. Discard remaining cobs. Slice bottom inch off lemongrass stalk and discard. Cut a 3″ piece off the bottom to use. Peel and discard firm outer layers of stalk until center portion is exposed. Finely slice center portion and reserve. Combine chopped cobs with coconut milk, chicken stock, lemongrass and ginger in stockpot over high heat. Bring to boil. Reduce heat and simmer 10 minutes to release flavors. Remove from heat and allow to cool. Remove cobs and discard.
2. Heat oil in saucepan over medium heat. Add shallots and cook 2 minutes, or until soft. Add corn kernels and cook until tender, approx. 8 minutes. Season with salt and pepper. Remove from heat. Combine half the corn mixture with half the coconut milk mixture in blender. Purée until very smooth. Pour through fine sieve into large bowl. Repeat with remaining corn and coconut milk.
3.  Stir fish sauce, 2 tbsp basil and 1⁄2 cup crab meat into soup. Season with salt and pepper. If soup is too thick stir in more stock. Refrigerate until cold, 2 to 3 hours. Taste and adjust seasoning.
