Special Soup - cooking recipe

Ingredients

1 medium celery knob (substitute 3 to 4 stalks celery)
2 small leeks
2 medium onions
distilled water (to cover vegetables)
1 medium parsley root
garlic as desired
1 1/2 lb. tomatoes or more

Preparation

Do not peel any of these vegetables; just wash, scrub them well and cut them coarsely.
Simmer them slowly for 2 hours, then put through food mill in small portions; scarcely any fibers should be left.
Vary the amount of water used for cooking according to taste and desired consistency.
Keep well covered in refrigerator, no longer than 2 days; warm up as much as needed each time.
