Crushed Tomatoes — NCHFP
Ingredients
- 22 lb Ripe tomatoes average for 7 quarts; about 14 lb for 9 pints
- 2 tbsp per quart Bottled lemon juice or 1 tbsp per pint; required. Citric acid alternative: 1/2 tsp per quart or 1/4 tsp per pint.
- 1 tsp per quart Canning or pickling salt optional
Equipment
- 1 Boiling-water canner or pressure canner Use one complete tested NCHFP processing option.
- 7–9 Pint or quart canning jars About 7 quarts or 9 pints per canner load.
- 7–9 Two-piece canning lids Use new flat lids and prepare according to manufacturer directions.
Directions
- Wash tomatoes. Dip in boiling water 30–60 seconds or until skins split, then dip in cold water. Slip off skins, remove cores, trim bruised portions, and quarter.
- Heat about one-sixth of the quarters quickly in a large pot, crushing them as they are added. Once boiling, gradually add the remaining quartered tomatoes while stirring constantly.
- Boil gently 5 minutes after all tomatoes are added.
- Add required bottled lemon juice or citric acid to each jar. Add salt if desired.
- Fill hot jars immediately with crushed tomatoes, leaving 1/2-inch headspace.
- Boiling-water process pints 35/40/45/50 minutes and quarts 45/50/55/60 minutes at 0–1,000/1,001–3,000/3,001–6,000/above 6,000 ft. Pressure-canning alternatives must follow the NCHFP table exactly; acidification is still required.

Frequently asked questions
Can I change the ingredients or process?
Only make changes expressly permitted by the authoritative source. Required bottled lemon juice or citric acid applies to every processing method. Do not add low-acid vegetables, thicken, or improvise processing.
What if a jar does not seal?
Refrigerate promptly, or reprocess within 24 hours using a new lid and the complete tested process if the source and current food-safety guidance permit.
How this recipe compares
Crushed tomatoes retain pulp and texture, unlike strained tomato juice or whole tomatoes packed in liquid.
Troubleshooting
Keep the mixture boiling while adding tomatoes in stages to reduce separation and achieve the documented hot pack.
Discard any jar that is leaking, bulging, spurting, moldy, or otherwise shows signs of spoilage. Never taste food to determine safety.
