  • Prepare Tomatoes. While the vegetables are simmering, cut the tomatoes, removing stems if not using a strainer. Add them to the kettle and cook until tender.

  • Strain Mixture. Pass the cooked vegetables and tomatoes through a Victorio strainer (or similar) to remove skins and seeds. Return the strained mixture to the kettle.

  • Make Roux. In a separate bowl, cream the butter and flour together. Mix thoroughly with two cups of COLD juice until dissolved (to avoid lumps). Add this roux to the warmed tomato mixture before it gets hot, stirring well.

  • Heat. Warm the mixture just until hot, avoiding a boil to prevent flour lumps. The mixture will continue to thicken as it cools.

  • Pressure can. Process pint jars in a pressure canner at 10 pounds of pressure for 15 minutes, adjusting for altitude. Check your pressure canner's manual for quart jars and for adjustments based on your location.
