Classic Tomato Sauce Canning: A Step-by-Step Guide

Canning homemade tomato sauce is a fulfilling way to preserve the flavors of summer and enjoy them throughout the year. Whether you have a bountiful harvest from your garden, or you’ve simply picked up a bushel of ripe tomatoes at the market, this guide will walk you through the process of making and canning classic tomato sauce.

Why Can Tomato Sauce?

Canning tomato sauce not only extends the shelf life of your produce, but it also allows you to customize flavors and avoid preservatives found in store-bought versions. Plus, there’s nothing quite like the taste of your homemade sauce, which is rich in flavor and free from artificial ingredients.

Ingredients You’ll Need

To create a classic tomato sauce, gather the following ingredients:

• Tomatoes: Ripe, fresh tomatoes are the star of the show. Varieties like Roma or San Marzano are perfect for sauce-making.
• Onions: They add depth of flavor to the sauce.
• Garlic: Fresh garlic infuses the sauce with aromatic goodness.
• Olive oil: For sautéing the onions and garlic.
• Fresh herbs: Basil, oregano, and parsley enhance flavor.
• Salt and pepper: To taste.

Equipment Required

Before you begin, make sure you have the following equipment:

• Canning jars: Pint or quart jars work well.
• Lids and bands: New lids are necessary for sealing jars.
• Water bath canner: Essential for safe canning.
• Canning funnel: Helps to fill jars without spilling.
• Jar lifter: For safely removing hot jars from the water.
• Ladle: For pouring the sauce into jars.

Step-by-Step Instructions

Step 1: Prepare the Tomatoes

1. Wash and Core: Rinse your tomatoes thoroughly, removing any stems and blemishes.
2. Blanch and Peel: Bring a pot of water to a boil, then immerse tomatoes for about 30 seconds. Transfer them to an ice bath to cool down. The skins will slip off easily.
3. Chop: Dice the peeled tomatoes, ensuring to catch the juices.

Step 2: Cook the Sauce

1. Sauté Aromatics: In a large pot, heat olive oil over medium heat. Add chopped onions and sauté until translucent. Then, add minced garlic and cook for another minute.
2. Add Tomatoes: Stir in the chopped tomatoes, salt, pepper, and fresh herbs. Bring the mixture to a gentle simmer.
3. Reduce and Thicken: Let the sauce simmer for at least 30 minutes, stirring occasionally. You want it to reduce and thicken while concentrating the flavors.

Step 3: Can the Tomato Sauce

1. Prepare Your Jars: While the sauce is simmering, sterilize your canning jars and lids by boiling them in water for 10 minutes.
2. Fill the Jars: Using a ladle and canning funnel, carefully fill each jar with hot tomato sauce, leaving about 1/2 inch of headspace.
3. Seal: Wipe the rims of the jars with a clean cloth to remove any residue. Place a sterilized lid on each jar and screw on the band until fingertip-tight.

Step 4: Process the Jars

1. Water Bath Canner: Place the jars in the canner filled with boiling water. Ensure water covers the jars by at least an inch.
2. Process: Let the jars boil for 35 minutes for pints, and 45 minutes for quarts. Adjust time according to your altitude if necessary.
3. Cool Down: Once processed, carefully remove the jars with a jar lifter and let them cool on a clean kitchen towel or rack.

Step 5: Check Seals and Store

1. Check the Seals: After 24 hours, press down in the center of each lid. If it doesn’t pop back, the jar is sealed. If it does, refrigerate and use within a week.
2. Store: Label the jars with the date and store them in a cool, dark place. Your homemade tomato sauce can last for up to a year.

Canning tomato sauce is a rewarding process that allows you to capture the essence of summer in a jar. With the right ingredients and careful techniques, you can create a delicious homemade sauce that elevates your cooking all year long.
