Pink Potato Soup - cooking recipe

Ingredients

3 large potatoes, cubed
1 celery rib, diced fine
1 carrot, diced fine
1 onion, diced fine
4 cups milk
2 teaspoons salt
1/2 teaspoon pepper
1 tablespoon parsley
1 cup sour cream
2 tablespoons flour
2 teaspoons paprika

Preparation

Boil potatoes, celery, carrot and onion in 1/2 cup water in a covered saucepan for 20 minutes. **Note per 1st review: If veggies are not diced in a VERY fine dice, this will need more than 1/2 cup water to cook. Use water to cover, more if needed.**.
Add milk, salt, pepper and parsley; bring just to boiling point.
Mix sour cream, flour and paprika.
Remove 1 cup hot mix from pan, stir into sour cream mix, return all to pot.
Cook, stirring constantly until bubbly and flour has thoroughly cooked (or soup will have a \"floury\" taste).
