Canning Whole Tomatoes (packed in water)
Procedure for hot or raw tomatoes filled with water in jars: Wash tomatoes. Dip in boiling water for 30 to 60 seconds or until skins split; then dip in cold water. Slip off skins and remove cores. Leave whole or halve. Add bottled lemon juice or citric acid to jars (See acidification directions). Add 1 teaspoon of salt per quart to the jars, if desired.
Raw pack — Heat water, for packing tomatoes, to boiling. Fill hot jars with prepared raw tomatoes, leaving 1/2-inch headspace. Cover tomatoes in the jars with boiling water, leaving 1/2-inch headspace.
Hot pack — Put prepared tomatoes in a large saucepan and add enough water to completely cover them. Boil tomatoes gently for 5 minutes. Fill hot jars with hot tomatoes leaving 1/2-inch headspace. Add cooking liquid to the jars to cover the tomatoes, leaving 1/2-inch headspace.
