In a dutch oven or large soup pot with a lid, heat the oil over medium heat. Add the chopped onion, potato and chilli. Saute for 5-7 minutes, until just starting to sweat. Add the corn cobs and the vegetable stock. Put the lid half on and simmer on medium-low heat for 25-30 minutes, or until the potatoes and corn kernels have softened.
1 tablespoon olive oil, 1 onion, 1 potato, 1 chilli, 3 corn cobs, 1 litre stock
Remove the corn cobs from the pot, and using a sharp knife, carefully slice off the kernels. Return the kernels to the potato mixture in the pot.
Using an immersion blender or a blender, blend the soup until smooth.
Lower the heat and add the cream, mixing well, and cook until heated through again.
