Tomato Soup For Canning - cooking recipe

Ingredients

4 lbs tomatoes
8 onions
14 stalks celery
3 bay leaves
2 cups water
1/2 lb butter
3 tablespoons salt, canning
1 cup sugar
1 1/2 cups flour

Preparation

Cook all vegetables together.
When done, sieve until like a smooth paste.
Add remaining ingredients and cook until thick.
Seal in glass jars while hot.
I would process in pressure cooker myself for about 90 minutes.
I'm guessing this to be safe however, it may be less time.
