Canned Raw Tomatoes
Ingredients
- Placeholder
Directions
- Ensure jars are not chipped or cracked. Sterilize jars in boiling water for 15 minutes.
- Prepare lids according to manufacturer’s specific instructions.
- Dip tomatoes into boiling water for 30 – 60 seconds or until skins split. Dip into cold water, slip off skins and remove cores. Leave whole or halve.
- Add a specified amount of acid to hot sterilized jars to acidify the tomatoes:
- Pints (500 mL): Use ¼ tsp citric acid or 1 tbsp bottled lemon juice or 2 tbsp pure white vinegar and 1 tsp sugar (sugar optional).
- Quarts (1 L): Use ½ tsp citric acid or 2 tbsp bottled lemon juice or 4 tbsp pure white vinegar and 2 tsp sugar (sugar optional).
- Pack raw tomatoes into jars, pressing until spaces between them fill with juice. Leave a generous ½ inch headspace. Do not overpack the jars. If you don’t have enough tomatoes to achieve the proper ½ inch headspace, use boiling hot tomato juice to fill. Remove air bubbles with a narrow rubber spatula or plastic knife. If necessary, add boiling hot tomato juice to maintain headspace. Wipe jar rims thoroughly with a clean damp cloth.
- Seal jars and submerge in a boiling water canner that is filled with hot, but not simmering, water. Ensure that the water covers the filled jars by 1 – 2 inches. For both pint and quart jars, process in a boiling water bath for 90 minutes in the Edmonton area.
- Without tilting jars, remove from boiling water bath and set on a cooling rack, dry towels or a cutting board.
- After 24 hours, check to see if lids have sealed. Lids should be curved downwards. Refrigerate any unsealed jars.
- Label sealed jars with contents and date. Screw bands may be removed from cooled jars. Store jars in a cool dry place for up to one year.
Tip: Sterilization and processing times are for the Edmonton area altitude of 2200 ft/671 m. If canning outside the Edmonton area, adjustments in time and pressure may be necessary for different altitudes. For altitudes higher than 3000 ft/914 m (Banff, Calgary, Jasper, Lethbridge areas), add 5 minutes to sterilizing and boiling water bath processing times.
