One potato, two potato, three potato.... chowder

Every time I see the word chowder I think of the Simpsons and laugh.
Its cold out, like really cold, close to 50 below every day. Nothing seems to warm a person up like a soup does. It must bring back memories of childhood fun, spending hours in the snow and coming in to warm up with Mom or Grandma's soup.
Today, I made chowder. I wanted something a little thicker to keep our tummies warmer, longer.

Ingredients

6-8 slices of bacon, cut into small pieces
2 celery stalks sliced
1 onion sliced
1tsp Rosemary
1/2tsp pepper

2tbsp flour
4 cups of broth (chicken or vegetable)

4 large potatoes cubed
1 tsp thyme

1-2cup of milk

In a large pot, cook your bacon, drain, keeping your grease. Toss sliced onion and celery into the grease and cook until the onion is translucent. Add rosemary and flour. Let your roux cook for a minute. Add 1 cup of broth, whisk together and let cook for a minute or two. Add the potatoes, and the rest of the broth. Cook potatoes. Slightly mash in the broth after they have cooked. Add the thyme and bacon back in at this point, let stand for a minute before adding milk. Add seasonings if required.
As Always, Happy Eating!
