Boil a large pot of water for the corn. Boil for 10 minutes. Let cool.
Once the corn cools, cut the corn off of the cobs. Keep the cobs.
Heat the olive oil in a large soup pot over low. Add the onion and garlic. Saute for 8-10 minutes, or until the onion is golden.
Add the whiskey and deglaze the pot. Let it cook for 1-2 minutes.
Add the corn cobs, corn, potatoes, vegetable broth, water, paprika, white pepper, and salt.
Bring to a simmer. Cover and cook for 40 minutes.
While the soup is simmering, cook the bacon. Let it cool and then cut or crumble it into small pieces.
Remove the corn cobs and add the heavy cream, bacon, and green onions.
In a small bowl, mix the cornstarch with 4 tablespoons of cold water. Add it to the soup and let it simmer for an additional 10 minutes
