What is Sweet Relish?

Sweet relish is a preserved condiment made from finely diced cucumbers, peppers, and onions that have been pickled in a sweet and tangy brine. The mixture gets its distinctive flavor from sugar, vinegar, and warming spices like mustard seed, celery seed, and turmeric. Unlike dill pickles or other savory preserves, sweet relish has a noticeably sweeter taste that makes it the perfect topping for hot dogs, burgers, and sandwiches.

Homemade Sweet Relish Ingredients

See the recipe card below for a complete list of ingredients and measurements.

• Medium Pickling Cucumbers – These smaller cucumbers are ideal for relish because they have fewer seeds and a firmer texture than regular cucumbers. You’ll need six medium ones, and the color will determine the final shade of your relish.
• Red Bell Pepper – One red bell pepper adds a touch of sweetness and beautiful color to your relish. The red variety is naturally sweeter than green peppers.
• Yellow Bell Pepper – The yellow pepper contributes a mild, fruity flavor that balances the red pepper. Using both creates a more complex flavor profile than using just one type.
• Large White Onion – White onions provide a sharp, clean flavor that mellows during the soaking and cooking process. One large onion is plenty to add depth without overpowering the other vegetables.
• White Granulated Sugar – The sugar is what makes this a sweet relish rather than a savory pickle. You’ll need 1½ cups to achieve that classic sweet relish taste.
• Apple Cider Vinegar – This provides the tangy pickle flavor and acts as the preserving agent. Apple cider vinegar has a slightly fruity taste that works beautifully with the vegetables.
  Pickling Salt – Pickling salt is pure salt without additives, which keeps your relish clear and prevents cloudiness. You’ll use ¼ cup for the initial soak to draw out excess moisture.
• Mustard Seed – Half a tablespoon of mustard seeds adds a subtle spicy note and that traditional pickle flavor. They also add a pleasant texture to the finished relish.
• Celery Seed – One teaspoon of celery seed brings an earthy, slightly bitter note that balances the sweetness. It’s a classic pickling spice that adds complexity.
• Turmeric – Just half a teaspoon of turmeric gives your relish that characteristic golden color and a subtle earthy flavor. It’s a traditional ingredient in many pickle recipes.
• Water – You’ll need enough water to cover the vegetables during the initial two-hour soak. This step helps remove excess moisture and prepare the vegetables for pickling.

Substitutions and Additions

• Green Bell Peppers – If you prefer a more traditional look or want a slightly less sweet flavor, swap out the red and yellow peppers for green bell peppers.
• Red Onion – Try using red onion instead of white for a slightly sweeter, more colorful relish.
• Jalapeño Peppers – Add one or two finely diced jalapeños (seeds removed) for a spicy sweet relish with a kick.
• Brown Sugar – Substitute half of the white sugar with brown sugar for a deeper, more molasses-like sweetness.
• White Vinegar – Use white vinegar instead of apple cider vinegar if you prefer a sharper, more acidic flavor.
• Extra Seeds – Leave some cucumber seeds in if you don’t mind them and want a more textured relish.

How to Make Sweet Relish (step-by-step directions)

STEP 1. Start by washing and thoroughly drying all your vegetables. Remove the seeds from the cucumbers and peppers, then finely dice the onions, cucumbers, and bell peppers into small, uniform pieces. Place all the diced vegetables in a large pot and sprinkle them with the ¼ cup pickling salt, stirring to coat evenly.

STEP 2. Fill the pot with water just enough to cover the vegetables, then cover the pot and let the vegetables soak for 2 hours. Once the vegetables are finished soaking, pour them into a large strainer, rinse them well under cold water, and let them drain completely.

STEP 3. Rinse your pot and place the apple cider vinegar and white granulated sugar in it. On medium heat, bring the mixture to a boil, stirring until the sugar has completely dissolved. Add the mustard seed, celery seed, and turmeric to the pot and stir, then boil for an additional two minutes.

STEP 4. Reduce the heat to low and add the drained vegetables. Bring the mixture to a simmer and cook for an additional 10 minutes, stirring occasionally. The vegetables should soften slightly but still retain some texture.

STEP 5. Spoon the hot relish mixture into three clean mason jars (two 32-ounce jars and one 8-ounce jar). Ensure that the liquid is distributed evenly among the jars, rather than adding too much to just one. Place the lids on tightly.

For Canning (Water Bathing): Water-bathe the jars for 10 minutes, with water reaching an inch above the jars while processing. Let them sit at room temperature with rings on for 24 hours, then remove the rings and check the lids for proper sealing. If they’re sealed properly, store them in the pantry until needed. After opening, store the jar in the fridge for optimum freshness.

For the Refrigerator Method: Allow the jars to cool on the counter until they reach room temperature, approximately 2 hours. Re-tighten the lids and place them in the fridge. Let them remain in the fridge for 3 days before use for the best flavor development. Keep in the fridge for up to 3 months in sealed mason jars.

Recipe Tips

• Cucumber Color Matters – The color of your garden-fresh cucumbers will directly affect the final color of your relish. Darker green cucumbers produce a deeper green relish, while lighter ones create a more yellow-green shade.
• Sweeter Peppers Preferred – While green bell peppers work fine, sweeter red and yellow peppers create a more balanced flavor profile that complements the sugar in the brine.
• Seed Preference – If your cucumbers don’t have many seeds and you enjoy a bit of extra texture, feel free to leave some seeds in. However, if they’re loaded with seeds, remove at least most of them for better texture.
• Uniform Dice – Take time to dice all vegetables into similar-sized pieces so they pickle evenly and create a consistent texture throughout.
• Don’t Skip the Soak – The 2-hour salt-water soak is essential for drawing out excess moisture and ensuring your relish has the proper texture, not too watery.
• Wait Before Tasting – For the refrigerator method, resist the urge to try it right away. The flavors need those 3 days to properly develop and meld together.

Storing Tips

• Storage – Properly canned sweet relish using the water bath method can be stored in your pantry at room temperature for up to one year in unopened jars.
• Refrigerator – Once a jar has been opened, store it in the refrigerator and use within 2-3 months for best quality. The refrigerator method relish should stay refrigerated at all times and will keep for up to 3 months.
• Freezing – While you can technically freeze sweet relish, it’s not recommended as the texture may become mushy when thawed. The refrigerator or canning methods are much better options.
• After Opening – For water bath canned relish, once you break the seal and open a jar, treat it like the refrigerator method version and keep it chilled, using within a few months.
