Red, green or yellow, tomatoes are versatile and nutritious

Reading Time: 4 minutes

My summer ritual is making tomato sauce with friends. We make a simple sauce and process it in a hot water bath to preserve it for the winter. After a long day of food preparation, I make pasta and we dip into our vat of freshly made sauce.

Pick tomatoes when they are firm but not hard because they continue to ripen after they are picked. When buying, avoid ones that have bruises or cuts on the skin and keep tomatoes separate from raw meat, poultry and seafood in the grocery cart.

Hot Water Bath Processing

This method of food preservation is suitable for food with a pH of 4.6 or lower. Tomatoes are borderline so add a teaspoon (5 mL) of lemon juice or citric acid to each two cup (500 mL) jar. If the recipe contains vinegar, there will be enough acid to safely process.

  • Slide non-metallic utensil down the inside of jars to remove any air bubbles, then readjust headspace.
  • Wipe rim of each jar, place lid on jar and apply screw band only until resistance is met. Do not over tighten.
  • Place in canner of boiling water. Adjust water level so jars are covered by at least one inch (2.5 cm).
  • When process time has elapsed, turn off heat and remove jars without tilting.
