📦 Ingredients
For 6-8 Pints:
- 🍅 15-18 lbs ripe tomatoes – Roma or paste tomatoes work best
- 🧅 2 cups chopped onions – about 2 medium onions
- 🧄 4 cloves garlic – minced
- 🌿 2 tablespoons olive oil
- 🌿 1 tablespoon dried oregano
- 🌿 1 tablespoon dried basil
- 🧂 Salt and pepper – to taste
- 🍋 Bottled lemon juice – 1 tablespoon per pint jar
💡 Pro tip: "Bottled lemon juice ensures consistent acidity for safe canning."
📝 Step-by-Step Instructions
Step 1 – Prep the Tomatoes
- Wash tomatoes. Cut an "X" on the bottom of each tomato.
- Blanch in boiling water for 30-60 seconds, then plunge into ice water.
- Peel skins, remove cores, and chop roughly.
💡 Pro tip: "Blanching makes the skins slip right off – it's the easiest way to peel tomatoes."
Step 2 – Cook the Sauce
- In a large pot, sauté onions and garlic in olive oil until soft.
- Add chopped tomatoes, oregano, basil, salt, and pepper.
- Simmer for 30-45 minutes until tomatoes break down and sauce thickens.
Step 3 – Blend (Optional)
- For a smooth sauce, use an immersion blender or transfer to a blender in batches.
Step 4 – Prepare Jars
- Sterilize jars and keep them hot.
- Add 1 tablespoon bottled lemon juice to each pint jar.
Step 5 – Fill and Process
- Ladle hot sauce into jars, leaving ½ inch headspace.
- Remove air bubbles, wipe rims, apply lids.
- Process in a boiling water bath for 35 minutes (adjust for altitude).
⚠️ Important: "Add 1 tablespoon lemon juice to each pint jar – this is essential for safe canning."
Step 6 – Cool and Check Seals
- Remove jars and cool for 12-24 hours.
- Check seals – lids should not flex when pressed.
🥫 Canning Guide
Why Lemon Juice is Required:
- 🍋 Tomatoes are borderline acidic – lemon juice ensures safe acidity

- ⏱️ Processing time: 35 minutes for pints at 0-1,000 ft
Altitude Adjustments:
- 0 – 1,000 ft: 35 minutes

- Above 6,000 ft: 50 minutes
🔧 Troubleshooting
