Ingredients

• 25 pounds Fresh Roma tomatoes
• 12 ounces Tomato paste
• 2 medium, diced Yellow onions
• 6 minced Garlic cloves
• 2 tablespoons Olive oil
• 1 cup White vinegar
• 3 tablespoons Granulated sugar
• 1 tablespoon Salt
• 2 teaspoons Dried oregano
• 2 teaspoons Dried basil
• 0.5 teaspoons Crushed red pepper flakes
• 1 teaspoon Black pepper
• 2 tablespoons Lemon juice

Directions

Step 1

Prepare the tomatoes by washing them thoroughly, removing the cores, and scoring an 'X' on the bottom of each tomato.

Step 2

Blanch the tomatoes in boiling water for 30-60 seconds, then transfer them to an ice-water bath. Peel off the skins and chop the tomatoes.

Step 3

In a large stockpot, heat the olive oil over medium heat. Add the onions and sauté until translucent, about 5 minutes.

Step 4

Add the minced garlic and cook for an additional 1-2 minutes until fragrant.

Step 5

Stir in the chopped tomatoes and bring the mixture to a simmer over medium-high heat.

Step 6

Lower the heat to medium-low and cook the tomatoes for about 90 minutes, stirring occasionally, until they break down and the sauce thickens slightly.

Step 7

Use an immersion blender or transfer the mixture to a blender in batches to puree until smooth (optional, for a smoother sauce).

Step 8

Return the sauce to the pot and stir in the tomato paste, white vinegar, sugar, salt, oregano, basil, crushed red pepper flakes, black pepper, and lemon juice.

Step 9

Simmer the sauce over low heat, uncovered, for another 60-90 minutes, stirring occasionally. Adjust seasoning as needed.

Step 10

Sterilize your canning jars and lids according to proper canning guidelines.

Step 11

Add 1 tablespoon of bottled lemon juice per pint jar (or 2 tablespoons per quart jar) to ensure safe acidity levels for canning.

Step 12

Ladle the hot sauce into the prepared jars, leaving 1/2 inch of headspace at the top.

Step 13

Wipe the jar rims clean, place the lids on, and tighten the rings until just snug.

Step 14

Process the jars in a boiling water bath canner for 35 minutes (adjust for altitude if necessary).

Step 15

Carefully remove the jars from the canner and let them cool completely on a towel-lined counter for 12-24 hours before checking the seals.

Step 16

Store sealed jars in a cool, dark place for up to 1 year. Refrigerate any unsealed jars and use within a week.
