Authentic Mimi's Cafe Corn Chowder

This is the actual recipe they use at Mimis!

4 tbs butter
6 tbs onion, chopped
3/4 cups celery, large diced
2 1/2 cups hot water
2 cups raw potato, peeled and cut into 1/2" cubes
3 cups frozen corn (i use super sweet)
2 tbs sugar
2 tsp salt
3 tbs flour
1 quart half and half

On meduim heat, melt butter and simmer onion and celery for 5 minutes until soft, but not brown.

Add water, potato, corn, and seasonings. Cover and simmer for 30 minutes or until potatoes are barely tender. (for me, this only takes 20 min.)

Whisk flour into 1 cup of half and half and stir into soup. Add the remaining 3 cups of half and half. Simmer for about 15 minutes, until the soup has thickened to a creamy consistency.

Correct the seasoning with additional salt and pepper, if needed. Correct the consistency if needed. To make the soup thinner add a little milk. To make the soup thicker simmer another 5-10 minutes.
