Step One
Cut the kernels off the corn cobs using a knife. Thinly slice the onion.
Step two
Heat the butter in a saucepan. Add the ingredients from step 1 and sauté.

Step three
Once the onion becomes tender, add the corn cobs and Kayanoya Original Vegetable Stock Powder, then pour in just enough water to barely cover the ingredients.

Step four
When the water has mostly evaporated, remove the corn cobs and dashi pack, then add the soy milk and gently heat.
Step five
Blend the mixture in a blender until smooth, strain through a fine sieve, and season with salt to taste.
