I found a variant of this recipe and decided to tweak it just a bit.
1/4 cup butter
1 whole onion, chopped
2 stalks celery, chopped fine
1/4 cup flour
2 tsp salt
2 cups fresh spinach, rough chopped
3-4 cups potatoes, chopped and peeled
5 cups water
1 cup heavy cream
Melt butter in large soup pot. Add onions and celery. Sautee until tender (about 12-15 mins).
Slowly incorporate flour and salt to cooked onions and celery. Add slowly and stir so as not to get lumps.
Add potatoes and water.
Stir constantly until boiling.
Once boiling, let simmer for 30 mins. Stirring occasionally.
After 30 mins (or potatoes are tender) add spinach and cream. Let cook 2 mins more.
** can be garnished with crumbled bacon, cheddar cheese, fresh chopped herbs or anything else you like.**
