In a heavy bottom, pot add the oil.
To this add the onions, garlic, ginger, and saute until translucent.
Add the sweet corn kernels and water.
Add in salt, mix, and bring the mixture to boil.
Once it starts boiling, switch the stove to slow and let the mixture simmer for 4-5 minutes.

Using a hand blender, blend the mixture to a semi coarse or smooth consistency as desired.
