Why This Recipe Works

This recipe is more than just throwing asparagus in vinegar. It’s carefully crafted to ensure both delicious flavor and safe preservation. Here’s why it works:

• Balanced Brine: The ratio of vinegar, water, salt, and sugar is crucial. The vinegar provides the acidity needed for preservation, while the salt and sugar balance the tartness and add flavor.
• Proper Acidity: Using a vinegar with at least 5% acidity is essential for food safety when canning. This acidity inhibits the growth of harmful bacteria.
• Blanching: Blanching the asparagus before packing helps to set the color, tenderize the spears slightly, and remove any lingering enzymes that could cause spoilage.
• Hot Packing: Packing the jars with hot asparagus and hot brine helps to create a stronger vacuum seal during processing, further ensuring safe preservation.
• Water Bath Canning: Water bath canning is a safe and effective method for preserving high-acid foods like pickled asparagus. The heat from the boiling water destroys any remaining microorganisms and creates a vacuum seal, preventing spoilage.

Ingredients

• 2 pounds fresh asparagus, trimmed to fit your jars
• 3 cups white vinegar (5% acidity or higher)
• 3 cups water
• 6 tablespoons canning salt (or kosher salt)
• 3 tablespoons granulated sugar
• 6 cloves garlic, peeled
• 6 teaspoons dill seeds
• 6 teaspoons mustard seeds
• Optional: 6 dried red chili flakes (or more, to taste)

Instructions

1. Prepare Your Canning Equipment: Wash canning jars, lids, and bands in hot, soapy water. Rinse well. Sterilize the jars by placing them in a large pot of boiling water for 10 minutes. Keep the jars hot until ready to fill. You can also sterilize them in a dishwasher with a sanitize cycle. Heat the lids in a small saucepan of simmering water (not boiling) to soften the rubber sealing compound.
2. Prepare the Asparagus: Wash the asparagus thoroughly. Snap off the tough ends. Cut the spears to fit your jars, leaving about ½ inch headspace at the top.
3. Blanch the Asparagus: Bring a large pot of water to a boil. Add the asparagus and blanch for 2-3 minutes, until bright green but still crisp. Immediately transfer the asparagus to an ice bath to stop the cooking process. Drain well.
4. Prepare the Brine: In a large saucepan, combine the vinegar, water, salt, and sugar. Bring to a boil, stirring until the salt and sugar are dissolved.
5. Pack the Jars: To each sterilized jar, add 1 clove of garlic, 1 teaspoon of dill seeds, 1 teaspoon of mustard seeds, and optional chili flakes. Pack the blanched asparagus tightly into the jars, leaving ½ inch headspace.
6. Add the Brine: Carefully pour the hot brine over the asparagus in each jar, leaving ½ inch headspace. Use a non-metallic utensil (like a plastic knife or bubble popper) to remove any air bubbles trapped in the jars. Wipe the jar rims clean with a damp cloth.
7. Seal the Jars: Place a lid on each jar and screw on a band until fingertip tight. Do not overtighten.
8. Process in a Water Bath Canner: Place the jars in a water bath canner fitted with a rack. Add enough hot water to cover the jars by at least 1 inch. Bring the water to a rolling boil.
9. Processing Time: Process pint jars for 10 minutes and quart jars for 15 minutes. Adjust processing time for altitude according to the chart below:
   • 0-1,000 feet: Pint Jars – 10 minutes, Quart Jars – 15 minutes
   • 1,001-3,000 feet: Pint Jars – 15 minutes, Quart Jars – 20 minutes
   • 3,001-6,000 feet: Pint Jars – 20 minutes, Quart Jars – 25 minutes
   • 6,001-8,000 feet: Pint Jars – 25 minutes, Quart Jars – 30 minutes
   • 8,001-10,000 feet: Pint Jars – 30 minutes, Quart Jars – 35 minutes
10. Cool and Check Seals: Turn off the heat and carefully remove the jars from the canner using a jar lifter. Place the jars on a towel-lined surface, leaving at least 1 inch between them. Let the jars cool completely, undisturbed, for 12-24 hours. As the jars cool, you should hear a “popping” sound as the lids seal.
11. Check the Seals: After 24 hours, check the seals. The lids should be concave and not flex when pressed. If a lid doesn’t seal, refrigerate the jar and use the pickled asparagus within a few weeks.

Tips for Success

• Use Fresh, High-Quality Asparagus: The fresher the asparagus, the better the flavor and texture of your pickled spears.
• Don’t Overcook the Asparagus: Blanching is important, but overcooking will result in mushy asparagus. Aim for bright green and slightly tender.
• Maintain Proper Headspace: Leaving the correct headspace is crucial for creating a proper vacuum seal.
• Remove Air Bubbles: Trapped air bubbles can interfere with the sealing process.
• Follow Processing Times Carefully: Accurate processing times are essential for food safety. Adjust for altitude as needed.
• Use Canning Salt: Canning salt is pure sodium chloride without any additives that can cloud the brine. If you use kosher salt, make sure it doesn’t contain any anti-caking agents.

Storage Instructions

Properly canned and sealed pickled asparagus can be stored in a cool, dark place for up to one year. Once opened, refrigerate and use within a few weeks.

FAQ

Q: Can I use a different type of vinegar?

A: White vinegar is recommended for its clear color and neutral flavor, allowing the asparagus flavor to shine. You can use apple cider vinegar, but it will darken the brine and impart a slightly different flavor. Do not use balsamic vinegar or other low-acid vinegars, as they are not safe for canning.

Q: Can I add other spices?

A: Yes, you can experiment with different spices to customize the flavor. Some popular additions include black peppercorns, coriander seeds, mustard seeds, or bay leaves.

Q: My pickled asparagus is soft. What did I do wrong?

A: Overcooking the asparagus during blanching or using old asparagus can result in a softer texture. Make sure to blanch the asparagus for only 2-3 minutes and use fresh, crisp spears.

Q: The brine is cloudy. Is it safe to eat?

A: Cloudiness can be caused by impurities in the salt or hard water. As long as the jars are properly sealed and the asparagus looks and smells normal, it is generally safe to eat. However, if you are unsure, it’s always best to err on the side of caution and discard the jar.
