is as easy to make as it is versatile to serve. The heat level is customizable to your personal preferences (I like mine mild, but feel free to go to town with the chili powder if that’s your thing!).
To “up” the smoky quality, you can certainly grill the corn instead of pan-roasting the kernels as directed below, but don’t skip the step of simmering the stripped cobs in the broth. I’ve always been amazed by how much sweet, milky deliciousness is hidden in the cobs themselves. They’re a natural flavor trove! I like to serve this soup hot as a light dinner, but have made something of a habit out of having the leftovers chilled for a refreshing lunch.
