In short
- Acid in every jar: per 1 L (quart) about 2 g of citric acid (½ teaspoon) or 30 mL (2 tablespoons) of bottled lemon juice.
- Sound, ripe, firm tomatoes; not from dead vines, not after frost, not overripe.
- Water bath: 35–45 min for juice, sauce and chopped; 85 min for whole tomatoes packed raw.
- Onion, peppers, carrots in the sauce = a low-acid sauce: pressure canner or freezer only.
- Roughly: 1.5 kg of tomatoes for 1 L of juice, 2.3 kg for 1 L of passata, 3 kg for 1 L of thick sauce.
