Fiery New Mexican Tomato Salsa for Canning: A Taste of Summer Preserved

The aroma of roasting chiles and simmering tomatoes always takes me back to my grandmother’s kitchen in Santa Fe. Every summer, she transformed the bounty of her garden into jars of vibrant salsa, each batch a little different depending on the whims of the harvest. Her salsa wasn’t just a condiment; it was a celebration of New Mexico’s unique flavors, bottled sunshine to brighten up the long winter months. This recipe, adapted from a New Mexico State University gem, captures that spirit of tradition and bold flavor. It’s a delicious and safe way to preserve the taste of summer for the entire year.

Recipe Overview

• Prep Time: 45 minutes
• Cook Time: 30 minutes
• Total Time: 1 hour 15 minutes
• Yield: 7-9 pints
• Dietary Type: Vegan, Gluten-Free

Ingredients

• 3 quarts tomatoes, peeled, cored, chopped (slicing type)
• 24 ounces tomato paste
• 3 cups onions, chopped
• 2 cups lemon juice (bottled only)
• 6 jalapenos, seeded, finely chopped
• 1 tablespoon salt
• 1 tablespoon sugar
• 4 long green chiles, seeded, chopped
• 1 tablespoon ground cumin (optional)
• 2 tablespoons oregano leaves (optional)
• 4 garlic cloves, finely chopped
• 1 teaspoon black pepper

Equipment Needed

• Large saucepan or stockpot
• Cutting board
• Sharp knife
• Measuring cups and spoons
• Ladle
• Pint jars (7-9)
• Jar lifter
• Boiling water canner
• Lids and rings for jars
• Magnetic lid lifter (optional)

Instructions

1. Prepare the Tomatoes: Begin by washing the tomatoes thoroughly. To peel them easily, score a shallow “X” on the bottom of each tomato and blanch them in boiling water for about 30-60 seconds, or until the skin starts to loosen. Immediately transfer them to an ice bath to stop the cooking process. The skins should slip off easily. Core the tomatoes and coarsely chop them.

2. Chop the Vegetables: Chop the onions and garlic finely. Seed the jalapenos and long green chiles and chop them as well. Be sure to use gloves when handling hot peppers to prevent skin irritation.

3. Combine Ingredients: In a large saucepan or stockpot, combine the chopped tomatoes, tomato paste, chopped onions, lemon juice, chopped jalapenos, chopped long green chiles, minced garlic, salt, sugar, black pepper, and optional cumin and oregano.

4. Simmer the Salsa: Bring the mixture to a boil over medium-high heat, stirring constantly to prevent sticking. Once boiling, reduce the heat to low and simmer for 30 minutes, stirring occasionally. This allows the flavors to meld and the salsa to thicken.

5. Prepare the Jars: While the salsa is simmering, prepare your canning jars. Wash the jars, lids, and rings in hot, soapy water. Rinse thoroughly. Keep the jars hot by simmering them in hot water until ready to fill. This prevents the jars from cracking when filled with hot salsa. Sterilize the lids according to the manufacturer’s instructions.

6. Fill the Jars: Using a ladle, carefully fill each hot jar with the hot salsa, leaving a 1/2-inch headspace (the space between the top of the salsa and the rim of the jar).

7. Remove Air Bubbles: Gently tap the jars on the counter or use a non-metallic utensil to release any trapped air bubbles. Add more salsa if needed to maintain the 1/2-inch headspace.

8. Wipe the Rims: Wipe the rims of the jars with a clean, damp cloth to remove any spills or food particles. This ensures a proper seal.

9. Place Lids and Rings: Place the sterilized lids on the jars, centering them carefully. Screw the rings on firmly, but not too tightly. You should be able to wiggle them slightly.

10. Process in a Boiling Water Canner: Carefully lower the filled jars into a boiling water canner using a jar lifter. The water should cover the jars by at least 1 inch. Bring the water to a rolling boil and process the jars for the following times, depending on your altitude:

    • 0-1,000 feet: 15 minutes
    • 1,001-6,000 feet: 20 minutes
    • Above 6,000 feet: 25 minutes

11. Cool and Check Seals: After processing, turn off the heat and let the jars sit in the canner for 5 minutes before removing them. Carefully lift the jars out of the canner using a jar lifter and place them on a towel-lined surface to cool completely. Do not tighten the rings.

12. Check the Seals: As the jars cool, you should hear a “popping” sound as the lids seal. After 12-24 hours, check the seals by pressing down on the center of each lid. If the lid flexes, it is not properly sealed and the jar should be refrigerated and consumed within a week or reprocessed with a new lid.

Expert Tips & Tricks

• Roasting the Vegetables: For a deeper, smokier flavor, roast the tomatoes, onions, garlic, and chiles before chopping and adding them to the salsa. This adds a layer of complexity to the final product.
• Adjusting the Heat: Feel free to adjust the amount of jalapenos and long green chiles to suit your taste. For a milder salsa, remove the seeds and membranes from the jalapenos. For a spicier salsa, leave the seeds in or add other hot peppers like serranos or cayennes.
• Using a Food Mill: For a smoother salsa, use a food mill to remove the skins and seeds from the tomatoes after they have been blanched and peeled. This will result in a silkier texture. Alternatively, you can quickly pulse quartered beefsteak/slicer tomatoes in a food processor with a shredding disc.
• Thickening the Salsa: If your salsa is too thin, you can add a small amount of cornstarch or arrowroot powder to thicken it. Mix 1 tablespoon of cornstarch or arrowroot powder with 2 tablespoons of cold water to create a slurry, then stir it into the simmering salsa.
• Acid is Key: Remember that lemon juice (bottled only) is critical for the safety of this canned recipe. Do not substitute with anything else.

Serving & Storage Suggestions

This New Mexican tomato salsa is incredibly versatile. Serve it with tortilla chips, tacos, burritos, enchiladas, or grilled meats. Use it as a base for soups, stews, or chili. It’s also delicious as a topping for eggs or as a condiment for sandwiches.

Properly canned jars of salsa can be stored in a cool, dark place for up to 1 year. Once opened, refrigerate and consume within 1-2 weeks.

FAQs (Frequently Asked Questions)

Q: Can I use fresh lime juice instead of bottled lemon juice?
A: No, bottled lemon juice is essential for food safety in this canned recipe because of its consistent acidity level. Fresh lime juice can vary in acidity, which could compromise the safety of your canned salsa.

Q: Can I reduce the amount of salt in this recipe?
A: While you can reduce the salt slightly to your liking, remember that salt is also a preservative. Reducing it too much may affect the shelf life of your salsa.

Q: My salsa is too spicy! How can I tone it down?
A: Stir in a tablespoon or two of sugar or a squeeze of lemon juice to balance the heat. You can also add more chopped tomatoes to dilute the spice.

Q: Can I use a different type of chili pepper?
A: Yes, you can substitute other types of chili peppers like serranos, cayennes, or poblanos based on your preferred spice level and flavor profile. Adjust the quantity accordingly.

Q: How do I know if my jars have sealed properly?
A: After cooling, the lid should be slightly concave and not flex when pressed in the center. If the lid flexes or you hear a popping sound when pressed, the jar is not properly sealed and should be refrigerated and used promptly.
