Slice off the corn kernels.
Mix all together with your hands and spread out evenly in a single layer. Roast the corn kernels at preheated oven at 450 ºF (230 ºC) degrees for 15 minutes. Once it's done, remove from the oven and set aside till Step 8.
Add the reserved cobs in the pot as they naturally sweeten the soup. Push the cobs down to see if they are covered with water. If not, add more water.
Bring to a boil over medium heat. Cover and lower the heat to medium-low heat and simmer for 15 minutes. During this time I highly recommend skimming the foam on the surface for more refined taste. After 15 minutes, discard the cobs.
Using an immersion blender, blend the soup until creamy and smooth. If you use a food processor or blender, let the soup cool for a few minutes before you start blending to avoid major splashes. Make sure to cover the hole with a towel when blending.
If you want to make your soup similar to corn potage (Japanese corn soup), strain the soup through a fine-mesh sieve for a smoother consistency.
Transfer the soup back to the pot and add heavy cream and milk. The ratio is entirely up to you. Here I used equal parts of milk and heavy cream, 1 cup each. Bring back to a simmer and cook uncovered for 10 minutes or more, stirring frequently. Once the water evaporates and it’ll be more flavorful.
Add kosher salt and freshly ground black pepper. Make sure to taste the soup when you season. I used roughly 1 ½ Tbsp kosher salt or so (I used up a total of 2 Tbsp kosher salt that I prepared for this recipe including salt I used for roasting corn and sautéing onion). Or individuals can decide how much salt they want for their personal serving. Finely chop parsley. Serve the soup hot or chilled. You can drizzle olive oil and/or heavy cream and sprinkle the parsley to garnish.
