How to Make It
In a blender or food processor, combine the corn kernels and 2 cups of the broth. Pulse to a coarse puree.
In a large pot, melt the butter over moderately low heat. Add the chopped onion and cook, stirring occasionally, until translucent, about 5 minutes.
Add the corn puree, the wine, the remaining 2 cups of broth, and the salt to the pot. Bring to a boil. Reduce the heat and simmer, stirring occasionally, until the corn is tender, 10 to 15 minutes. Add the milk and bring just to a simmer. Stir in the crabmeat and chives.
• Puree four cups (two ten-ounce packages) of defrosted frozen corn kernels with the milk (not the broth). Since frozen corn is already cooked, stir the puree into the soup when the milk is added in Step 3, bring just to a simmer, and then stir in the crabmeat and chives.
• Substitute half a pound of medium peeled shrimp for the crabmeat. Stir the shrimp in along with the milk and cook for three to five minutes.
