- Safe Canning Process: The recipe includes clear and concise instructions for proper canning techniques, ensuring that your pickles are safely preserved for long-term storage.
- Customizable: Feel free to adjust the amount of sugar or mustard to suit your personal preferences. You can also add other vegetables like cauliflower or green beans for a unique twist.
- Detailed Instructions: The step-by-step instructions are easy to follow, even for beginner canners. Each step is clearly explained, leaving no room for guesswork.
Ingredients
- 8 cups thinly sliced cucumbers (about 4-5 medium cucumbers)
- 2 cups thinly sliced onions (about 2 medium onions)
- 2 cups thinly sliced bell peppers (a mix of colors is nice)
- 1/4 cup pickling salt
- 4 cups white vinegar (5% acidity)
- 3 cups granulated sugar
- 2 tablespoons mustard seeds
- 1 tablespoon ground turmeric
- 1 teaspoon celery seeds
- 1/2 teaspoon ground cloves (optional)

Instructions
- Prepare the Vegetables: Wash and thinly slice the cucumbers, onions, and bell peppers. Place them in a large bowl.
- Salt Brine: Sprinkle the pickling salt over the vegetables and toss to combine. Add enough cold water to cover the vegetables completely. Cover the bowl and refrigerate for at least 4 hours, or preferably overnight. This step is crucial for drawing out excess moisture and ensuring crisp pickles.
- Prepare the Jars: While the vegetables are brining, prepare your canning jars. Wash and sterilize 6-8 pint-sized canning jars and lids according to manufacturer’s instructions. Keep the jars hot until ready to use.
- Make the Brine: In a large stainless steel saucepan, combine the white vinegar, sugar, mustard seeds, turmeric, celery seeds, and cloves (if using). Bring the mixture to a boil over medium-high heat, stirring constantly until the sugar is dissolved.
- Drain and Rinse Vegetables: Drain the vegetables from the salt brine and rinse them thoroughly under cold running water. This removes excess salt.
- Add Vegetables to Brine: Add the drained and rinsed vegetables to the boiling vinegar mixture. Bring the mixture back to a boil, then reduce the heat and simmer for 10-15 minutes, or until the vegetables are slightly softened but still crisp.
- Pack the Jars: Using a slotted spoon, pack the hot vegetables into the hot, sterilized jars, leaving 1/2 inch of headspace. Ladle the hot brine over the vegetables, ensuring that they are completely submerged and maintaining the 1/2 inch headspace.
- Remove Air Bubbles: Use a non-metallic utensil (like a chopstick or plastic spatula) to gently run around the inside of each jar to release any trapped air bubbles.
- Wipe Jar Rims: Wipe the rims of the jars with a clean, damp cloth to remove any spills or residue.
- Place Lids and Rings: Place the sterilized lids on the jars and screw on the rings until fingertip tight. Do not overtighten.
- Process in a Water Bath Canner: Place the jars in a boiling water bath canner. The water should cover the jars by at least 1 inch. Bring the water to a rolling boil and process for 10 minutes for pint jars, adjusting for altitude if necessary (add 5 minutes for 1,001-6,000 feet, and 10 minutes for above 6,000 feet).
- 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 and let them cool completely for 12-24 hours. As the jars cool, you should hear a “popping” sound as the lids seal. After 24 hours, check the seals by pressing down on the center of each lid. If the lid is concave and doesn’t flex, it is properly sealed.
- Label and Store: Label the jars with the date and contents. Store the sealed jars in a cool, dark place for at least 2 weeks before opening to allow the flavors to develop.
Tips for Success
- Use Fresh, High-Quality Vegetables: The quality of your vegetables will directly impact the flavor and texture of your pickles. Choose firm, unblemished cucumbers, onions, and bell peppers.
- Don’t Skip the Salt Brine: This step is essential for removing excess moisture and ensuring crisp pickles.
- Use Pickling Salt: Pickling salt is pure sodium chloride without any additives like iodine or anti-caking agents, which can cloud the brine and affect the flavor.
- Maintain Headspace: Proper headspace is crucial for creating a vacuum seal. Too little headspace can cause the jars to buckle or not seal properly, while too much headspace can lead to spoilage.
- Don’t Overtighten the Rings: Overtightening the rings can prevent air from escaping during processing, which can also lead to buckling or seal failure.
- Adjust Processing Time for Altitude: If you live at a high altitude, you will need to increase the processing time to ensure proper sealing.
- Wait Before Eating: Although tempting, resist the urge to open the jars immediately. Allowing the pickles to sit for at least 2 weeks allows the flavors to meld and develop fully.
Storage Instructions
Unopened jars of Sweet Mustard Pickles can be stored in a cool, dark place for up to 1 year. Once opened, store the pickles in the refrigerator and consume within 2-3 weeks.

FAQ
Q: Can I use a different type of vinegar?
A: While white vinegar is recommended for its neutral flavor and clarity, you can experiment with other types of vinegar, such as apple cider vinegar. However, be aware that this will alter the flavor of the pickles.
Q: Can I reduce the amount of sugar?
A: Yes, you can reduce the amount of sugar to suit your taste. However, keep in mind that sugar helps to preserve the pickles, so reducing it too much may affect their shelf life.
Q: What if my jars don’t seal?
A: If a jar doesn’t seal within 24 hours, you can reprocess it with a new lid and ring, or store it in the refrigerator and consume it within a few weeks.
Q: Can I use different vegetables?
A: Absolutely! Feel free to add other vegetables like cauliflower florets, green beans, or even jalapenos for a spicy kick.
