Bring chile, corn kernels, coconut milk, and water to a boil in a medium saucepan. Reduce heat, and simmer until corn is tender, about 20 minutes.
Filling a blender halfway and covering with a kitchen towel, puree soup in batches. Strain through a coarse sieve into a large bowl; discard solids. Season with salt and pepper.
Chill soup at least 3 hours or up to overnight. Stir in lime juice. Garnish each serving with fresh corn kernels if desired, and season with pepper.
Here I was with four fresh ears of corn from the farmstand and the coconut milk, so...I had a cup too much or corn and added it, chilled it overnight, and at first taste, I didn't feel the "wow" that I expected. But by the third bite, the light flavor of the chili showed up at the back of my throat, I could taste both the corn and the coconut, and I fell head over heels for the soup. In the second bowl I remembered the lime, and it was sensational! Wonderful combo of flavors with silky texture!
This is a wonderful soup; quick and easy with lots of flavor. I've made it twice and highly recommend trying this recipe. I do wish that nutritional values were included.
