Peel 15 potatoes, rinse, then place in a bowl with water and 1/2 tsp. of salt, then set aside. Place a large pot of water on the stove and bring to a boil. Finely cube the celery, garlic and onions. Then cube the potatoes. Place the potatoes into the pot and boil for 20 minutes. I use the Chop Wizard, it has two different sizes of blades.
Take a small sauce pan and place the butter into it. Cook on medium-high setting. Then, after butter starts to melt, add soy sauce, celery, and onions, until they are well-cooked and not crispy. Then add the garlic, do not cook any longer than 1 minute or it will loose all medicinal properties and just be a flavoring. Remove from heat. Pour the base into a large stock pot, add the sauce mixture, the corn and the 2 C. of potatoes you set aside. Cook for 6-8 minutes on medium-high stirring continuously. Then remove from heat, pour into bowls and serve.
