Fire-roasting tomatoes intensifies their flavor, giving them a smoky sweetness that's perfect for sauces, soups, and chili. Canning your own fire-roasted tomatoes lets you enjoy this taste throughout the year. This guide provides a detailed, step-by-step process to safely preserve the bounty of your garden or farmer's market.

Preparing Your Ingredients and Equipment for Canning Fire-Roasted Tomatoes

Before you begin, gather your ingredients and equipment. Proper preparation is key to successful canning. Improper preparation can lead to spoilage.

Ingredients:

  • Ripe tomatoes (Roma or other canning varieties work best)
  • Water
  • Salt (for brine)

Equipment:

  • Large roasting pan or grill
  • Canning jars (pint or quart size, depending on your preference)
  • Lids and rings for canning jars
  • Large pot for water bath canning
  • Jar lifter
  • Ladle
  • Funnel
  • Clean towels

Roasting the Tomatoes for that Smoky Flavor

Fire-roasting is what gives canned tomatoes their unique flavor. Here's how to do it:

Step 1: Preparing the Tomatoes

Wash your tomatoes thoroughly. Halve or quarter them, depending on size. Removing the core is optional, but it can help with even roasting.

Step 2: Roasting

Place the tomatoes cut-side down in your roasting pan. Roast in a preheated oven at 400°F (200°C) for 30-45 minutes, or until the skins are blistered and slightly charred. Alternatively, roast them directly on a grill until charred. This adds a deeper smoky flavor.

Step 3: Peeling (Optional)

While not strictly necessary, peeling the tomatoes after roasting removes the skins and creates a smoother consistency. Simply place the roasted tomatoes in a bowl of ice water for a few minutes. The skins will easily peel off.

Canning Your Fire-Roasted Tomatoes: A Safe and Simple Method

Once your tomatoes are roasted, it's time to can them. Follow these steps carefully to ensure food safety.

Step 1: Preparing the Jars

Wash the jars, lids, and rings thoroughly in hot, soapy water. Sterilize them in boiling water for at least 10 minutes. Keep them in hot water until ready to use. This prevents spoilage.

Step 2: Packing the Jars

Using a funnel, carefully pack the roasted tomatoes into the sterilized jars, leaving about ½ inch headspace at the top.

Step 3: Adding the Brine

Add 1 teaspoon of salt to each pint jar or 2 teaspoons to each quart jar. Top up the jars with boiling water, leaving that ½ inch headspace. Use a ladle to avoid splashing.

Step 4: Removing Air Bubbles

Run a non-metallic utensil (like a clean butter knife) around the inside of the jar to release any trapped air bubbles. Wipe the jar rims clean with a damp cloth.

Step 5: Sealing the Jars

Place the lids on the jars and screw the rings on fingertip tight. Don't over-tighten.

Step 6: Water Bath Canning

Place the filled jars in a large pot, ensuring they are covered by at least 1 inch of water. Bring the water to a rolling boil and process according to your altitude.

  • 0-1,000 feet: Process pints for 35 minutes, quarts for 45 minutes.
  • 1,001-3,000 feet: Process pints for 40 minutes, quarts for 50 minutes.
  • 3,001-6,000 feet: Process pints for 45 minutes, quarts for 55 minutes.

(Adjust processing times based on your altitude. Consult a reliable canning resource like the National Center for Home Food Preservation for precise times based on your location.)

Step 7: Cooling and Checking Seals

Carefully remove the jars from the pot using a jar lifter and let them cool completely undisturbed. You should hear a "pop" sound as the jars seal. Check the seals by pressing down on the center of each lid. If the lid doesn't flex, it's sealed properly.

Storing Your Canned Fire-Roasted Tomatoes

Once cooled and sealed, store your canned fire-roasted tomatoes in a cool, dark, and dry place. They should last for 12-18 months.

Troubleshooting and Tips for Success

  • Cloudy Tomatoes: This is usually due to air bubbles trapped during packing. Make sure to remove air bubbles thoroughly.
  • Spoiled Tomatoes: Don't use tomatoes that are bruised, overripe, or showing signs of spoilage.
  • Improper Sealing: If jars don't seal, check your process. Make sure jars are clean, lids are new, and headspace is correct. Improper sealing can lead to spoilage.
  • Altitude Adjustments: Always consult a reliable canning resource for accurate processing times based on your altitude. Altitude affects boiling point.

Canning your own fire-roasted tomatoes is a rewarding experience. Enjoy the delicious smoky flavor throughout the year! Remember, food safety is paramount, so always follow proper canning procedures. Happy canning!
