Potato Soup

I often make potato soup for us. Well yesterday was no different. I really have no set recipe per se. I start 4 quarts of water on the stove and then I go to chopping up my veggies. Which can include anything from carrots, radishes, celery, broccoli and when it is all done and ready to eat I will add spinach so it's not so wilted. I add about 6-8 potatoes, that I cut up into cubes along with the veggies I have already added to the water. Which I have already added all my spices while my veggies were cooking.
After about 1/2 an hour after the potatoes were put in I check to see that they are soft then in another pan I add 2 cups of milk and about 4-6 tablespoons of flour and mix well. This will help thicken the soup. After this starts to thicken I then add it to the soup mixture slowly. Stirring this all together.
I usually add cheese at this time to give it a cheesy flavor. But if you don't have any that is fine. And this is also when I add the spinach.
OH- I forgot to tell you that I just wash the potatoes and leave the peeling on them. We like it this way. But it's up to you.
