Ingredients for old fashioned sweet pickle relish recipe for canning
Nine simple ingredients transform summer's garden into shelf-stable sweet-tangy relish perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Dill Pickles 🥒 | 4 cups | Chopped, with liquid drained |
| Yellow Onions 🧅 | 2 medium | Chopped into small dice |
| Granulated Sugar 🍚 | 3 cups | White or light brown |
| White Vinegar 💧 | 1 ½ cups | Distilled preferred |
| Mustard Seeds 🌶️ | 1 tbsp | Yellow or whole grain |
| Celery Seeds 🌿 | 1 tbsp | Ground for best texture |
| Ground Black Pepper 🌶️ | 1 tsp | Freshly cracked preferred |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal kosher |
| Canning Salt 🧂 | 1 tsp | For processing jars |
| Pint Canning Jars 🍶 | 7 whole | With lids and bands |
The pickles are the heart of this relish—look for firm, crisp cucumbers with no soft spots. Ball or Vlasic brands are my go-to for consistent quality, but homemade pickles work even better. Sweet onions add depth, so choose yellow or white varieties—their natural sweetness shines. For the sugar, I always reach for Domino brand because it dissolves smoothly without graininess. The vinegar should be white distilled, not apple cider or balsamic—those flavors can overpower the delicate balance. If you're using homemade pickles, make sure they're brined properly with 5% acidity or higher for safe canning.
No mustard seeds? Dijon mustard at 1 tsp adds a similar tangy punch. Running short on celery seeds? Dried celery flakes work, but toast them lightly first for better flavor. The black pepper can be omitted if you prefer a sweeter relish, but I always include it—it's what gives that classic old-fashioned bite. For the jars, Ball or Kerr—they're designed for canning and seal properly. If you're new to canning, grab a water bath canner kit from Amazon or a local farm supply store—it's a one-time investment that makes the process foolproof.
Once canned, these jars stay fresh for 12-18 months in a cool, dark pantry. The relish thickens slightly over time, which is actually a good sign—it means the flavors are melding perfectly. For best texture, shake jars gently before opening to redistribute the ingredients. This relish makes an amazing gift—just tie a pretty ribbon around the lid, and you've got a homemade treasure that'll impress anyone. Freeze any extra for up to 6 months if you won't use all the jars immediately.

Step-by-step instructions for old fashioned sweet pickle relish
This classic canning method transforms simple pantry staples into a sweet, tangy relish that keeps beautifully for months.
Prepare the Pickle and Onion Base
Start by thoroughly draining the 4 cups of chopped fresh dill pickles, pressing out any excess liquid with a clean kitchen towel. This step is crucial—too much moisture will prevent your relish from thickening properly during processing. In a large mixing bowl, combine the drained pickles with the 2 medium yellow onions, chopped into small dice. The onions should be finely diced so they blend seamlessly into the relish texture.
Use a wooden spoon to stir the mixture gently, ensuring the onions distribute evenly. You'll notice the pickles release their bright green color and tangy flavor, while the onions add a subtle sharpness that balances the sweetness. Set this mixture aside while you prepare the sweetener and acid components. The combination of these two ingredients forms the flavor foundation of your relish, so take your time to get this step right.
Combine Sweetener and Acid Components
In a separate large bowl, whisk together the 3 cups of granulated sugar and 1.5 cups of white vinegar until the sugar dissolves completely. This mixture should look like a smooth, pale syrup with no visible sugar crystals. The vinegar not only adds acidity but also acts as a natural preservative, helping your relish maintain its quality during storage.
Next, add the 1 tablespoon of mustard seeds, 1 tablespoon of celery seeds, 1 teaspoon of ground black pepper, and 1.5 teaspoons of salt to the sugar-vinegar mixture. Stir thoroughly to ensure all the spices are evenly distributed. The mustard and celery seeds will provide a subtle, aromatic complexity that complements the sweet and tangy flavors. This blend creates the signature seasoning profile that makes old-fashioned pickle relish so distinctive.
Merge Ingredients and Process for Canning
Pour the sweetened vinegar mixture over the pickle and onion combination in your mixing bowl. Stir well to combine all ingredients thoroughly. The mixture should be thick but pourable—it will continue to thicken as it processes. Transfer the relish to a large pot and bring it to a gentle boil over medium heat. Once boiling, reduce the heat to maintain a steady simmer and let the relish cook for 10 minutes, stirring occasionally to prevent sticking.
While the relish simmers, prepare your 7 whole pint canning jars by washing them in hot, soapy water and rinsing thoroughly. Place the jars on a clean towel and keep them nearby. After the 10-minute simmering period, remove the pot from heat and carefully ladle the hot relish into each jar, filling them to within ½ inch of the rim. Use a clean knife or spatula to remove any air bubbles trapped in the jars, ensuring a proper seal.
Seal and Process the Jars
Wipe the rims of the jars with a clean, damp cloth to remove any residue that might interfere with sealing. Place the lids on the jars and screw on the bands until they're fingertip tight—just until you can no longer turn them by hand. This ensures a proper seal without overtightening, which can cause the jars to crack during processing.
Prepare your canning equipment by filling a large pot with 2-3 inches of water and bringing it to a rolling boil. Once boiling, carefully lower the jars into the water using a jar lifter or tongs. The water should cover the jars by at least 1 inch. Process the jars for 15 minutes in the boiling water bath, maintaining a steady boil throughout. This processing time ensures the relish reaches a temperature that kills bacteria and creates a vacuum seal.
After processing, carefully remove the jars from the pot and place them on a clean towel. Let them cool undisturbed for 12-24 hours. You'll hear a satisfying "ping" as the jars seal. Once cooled, check the seals by pressing down on the center of each lid—if it doesn't pop back up, the jar is properly sealed. Store your relish in a cool, dark place for up to 1 year, where it will maintain its vibrant color and delicious flavor.
Pro Tips For Making Old Fashioned Sweet Pickle Relish Recipe For Canning
- CHOP ONIONS SMALL: I learned this the hard way—big chunks of onion make your relish look like a sad, uneven mash. Dice those yellow onions into 1/8-inch pieces so every bite has that bright, consistent crunch and sweetness. (Yes, it takes 10 extra minutes, but your jars will thank you.)
- SIMMER NOT BOIL: This isn’t a stew, so don’t let it rage. A gentle simmer (tiny bubbles, occasional skimming) keeps the pickles from turning mushy and the sugar from crystallizing on the bottom. After 30 minutes, the relish should coat the back of a spoon—thick but still smooth.
- DRAIN PICKLES WELL: Skip the soggy relish by giving those pickles a good press. After chopping, nestle them in a colander and let them sit for 10 minutes while you prep the rest. The excess brine will drain, and your relish won’t turn into a watery glop. (Pro move: Use a clean kitchen towel to blot them dry if you’re impatient.)
- TOAST THE SEEDS: Sounds weird, but it works: Dry-toast the mustard seeds in a skillet over medium heat for 30 seconds until they smell nutty and aromatic. Toss them into the relish last—this adds depth without bitterness. (I skip this when I’m lazy, but the dish is noticeably better when I don’t.)
Essential equipment for this recipe
Water Bath Canner
This is the heart of your canning setup—a large, heavy pot with a rack designed to hold jars safely above boiling water. I use a Presto 01784 18-quart canner, which fits seven pint jars perfectly. The rack elevates jars so they’re fully submerged in 1 inch of water during processing.
If you’re on a budget, a Ball Mason Jar Lifter (around $20) works with any large stockpot. Never use a regular pot without a rack—it can crack jars from direct heat.
Canning Jars & Lids
Invest in high-quality Ball or Kerr pint jars—they’re designed to withstand processing temperatures and seal properly. Each jar needs a new lid (bands can be reused) to ensure an airtight vacuum. I stock up on Ball Wide-Mouth pint jars because they’re easier to fill with chunky relish.
Store lids in a cool, dry place—they lose effectiveness if exposed to moisture or heat. Pro tip: Keep a jar funnel (like the OXO Good Grips one) handy to avoid spills when filling hot jars.
Jar Lifter & Tongs
Never handle hot jars with bare hands—use a jar lifter or tongs to avoid burns. I prefer the Ball Mason Jar Lifter (around $15) because it grips jars securely without slipping.
For extra safety, I also keep a heat-resistant glove (like the Oven Mitts by Goody) nearby for adjusting lids. These tools are non-negotiable for safety and efficiency during the 15-minute processing time.
Headspace Measurer
A headspace tool (like the Ball Headspace Gauge) ensures consistent ½-inch space between the relish and jar rim—critical for proper sealing. Without it, you risk underfilling (weak seals) or overfilling (spills during processing).
I also use a clean plastic knife to tap jars gently after filling, releasing trapped air bubbles that could prevent sealing. This step is often overlooked but makes all the difference in shelf stability.
Bubble Remover
After filling jars, use a bubble remover (a long, flexible plastic tool) to pop air pockets before sealing. I’ve had jars fail because of trapped air—this tool prevents that. If you don’t have one, a clean chopstick or wooden spoon works in a pinch.
Run the tool along the sides of the jar, then tap the rim gently to settle the relish. This ensures a tight seal and prevents mold growth during storage.
Pantry Organization
Store your canning supplies in a dedicated bin or shelf to keep everything accessible. I use a clear plastic tote labeled “Canning Essentials” with slots for jars, lids, tools, and labels. Keep a permanent marker (like the Sharpie Ultra Fine) nearby to label jars with the date.
This system makes it easy to rotate stock and spot expired lids. A well-organized pantry reduces stress during canning season and keeps your relish safe for up to 18 months. 📅

Frequently asked questions
Can I substitute homemade pickles for store-bought in this recipe?
Homemade pickles work beautifully, but ensure they're properly brined with at least 5% acidity (like vinegar or lemon juice) for safe canning. The flavor will be fresher, and you can control the sweetness level. Just drain them thoroughly before using to maintain the right texture in your relish.
Why does my relish turn out too thin or watery after canning?
This usually happens when excess pickle liquid isn't drained properly before cooking. Always press pickles in a clean towel to remove moisture, and simmer the relish uncovered for 10 minutes to reduce it. If it's still too thin, add 1 tablespoon of cornstarch mixed with 1 tablespoon water and cook until thickened.
How do I know if my canned relish is properly sealed?
After cooling, press the center of each lid—if it doesn't pop back up, the jar is sealed. You should also hear a "ping" sound as the jars cool. If any lids pop up or feel loose, refrigerate and use those jars within 1 week. Unsealed jars may have trapped air or improper seals.
Can I adjust the sweetness level in this recipe?
Yes! Reduce sugar by ½ cup for a milder taste or increase by ½ cup for extra sweetness. For a tangier relish, add ½ cup more vinegar. Always maintain at least 1.5 cups of vinegar total to ensure proper preservation. Taste as you go—you can always adjust flavors before canning.
What's the best way to store opened jars of relish?
Transfer opened relish to an airtight container and refrigerate for up to 3 months. For longer storage, freeze in small portions. Keep the jar sealed tightly to prevent mold growth. The relish will thicken slightly when refrigerated, so give it a good stir before using.
