Instructions

  1. Chop onion& celery.
  2. Place in large kettle w/ just enough water to keep them from burning.
  3. While this simmers, cut tomatoes (remove stems if not using strainer).
  4. Add to kettle& cook until tender.
  5. Place this all through Victorio strainer (or similar).
  6. Return to kettle.
  7. Add sugar& salt.
  8. Cream butter and flour together& mix thoroughly with two cups of COLD juice, until dissolved (or blend together in a blender), to avoid lumps of flour in the juice.
  9. Add butter/flour mixture to warmed tomato juice. (Add before it's hot, to avoid lumps of flour!).
  10. Stir well.
  11. Heat just until hot. (If it gets to a boil, it can make the flour lumpy).
  12. Just prior to boiling, turn off the burner. (It will continue to thicken as it cools.).
  13. Ladle into jars& close securely with lids.
  14. Return to canner & process 20-30 minutes (start timing when it's at a 'rolling' boil).
  15. Remove from canner & allow to set until sealed (approx. 12 hours) To serve, mix equal parts tomato concentrate to milk, and add 1/2 t. of baking soda per pint as it cooks (1 t. per quart).
