Ingredients

• 20 pounds Ripe plum tomatoes
• 4 tablespoons Olive oil
• 2 pieces Large onions, diced
• 6 pieces Garlic cloves, minced
• 2 pieces Green bell peppers, diced
• 2 tablespoons Sugar
• 2 tablespoons Dried basil
• 1 tablespoon Dried oregano
• 2 tablespoons Salt
• 1 teaspoon Ground black pepper
• 1 teaspoon Red pepper flakes (optional)
• 12 ounces Tomato paste
• 1 tablespoon per jar Lemon juice (bottled for consistency)

Directions

Step 1

Wash the tomatoes thoroughly. Score a small 'X' on the bottom of each tomato and blanch them in boiling water for 1-2 minutes, then transfer to an ice water bath. Peel off the skins, core the tomatoes, and roughly chop them.

Step 2

In a large stockpot, heat the olive oil over medium heat. Add the diced onions and cook until softened, about 5-7 minutes. Add the minced garlic and cook for an additional 1-2 minutes until fragrant.

Step 3

Add the diced green bell peppers and cook for another 5 minutes until softened.

Step 4

Stir in the chopped tomatoes and bring the mixture to a simmer. Reduce the heat to low and let the tomatoes cook down for about 1 hour, stirring occasionally.

Step 5

Using an immersion blender or working in batches with a regular blender, puree the mixture until smooth (or leave it slightly chunky if preferred). Return the sauce to the pot.

Step 6

Stir in the tomato paste, sugar, dried basil, oregano, salt, black pepper, and optional red pepper flakes. Simmer the sauce uncovered for 2-3 hours, stirring occasionally, until it thickens to the desired consistency.

Step 7

Prepare your canning jars by washing them thoroughly and sterilizing them in boiling water. Keep the jars hot until ready to use.

Step 8

Ladle the hot spaghetti sauce into the sterilized jars, leaving 1/2 inch of headspace. Add 1 tablespoon of bottled lemon juice to each jar to ensure proper acidity for safe canning.

Step 9

Wipe the rims of the jars with a clean, damp cloth. Place the sterilized lids on top and screw on the rings just until finger-tight.

Step 10

Process the jars in a boiling water bath for 35 minutes (adjusting for altitude as needed). Ensure the water covers the jars by at least 1 inch.

Step 11

Remove the jars from the water bath and let them cool on a towel-lined counter for 12-24 hours. Check that the lids have sealed (they should not pop when pressed).

Step 12

Store the sealed jars in a cool, dark place for up to 1 year. Any unsealed jars should be refrigerated and used promptly.
