Ingredients You’ll Need

• 3 cups thinly sliced radishes (about 1½ lbs)
• 1 red onion, thinly sliced
• 2 tablespoons pickled jalapeños, seeded
• 2 garlic cloves, minced
• 1 cup apple cider vinegar
• ½ cup granulated sugar
• 2 teaspoons kosher salt
• 2 tablespoons yellow mustard seeds
• 1 teaspoon celery seeds
• ½ teaspoon dried dill

Ingredient Notes

Regular red round radishes from the grocery store work perfectly here. Look for firm radishes with fresh greens still attached if possible. Slice them thin and uniform so they pickle evenly. A mandoline makes this job quick, but a sharp knife works fine if you take your time.

Apple cider vinegar gives this relish its tangy bite, but white wine vinegar or rice vinegar work as substitutes if that’s what you have. The mustard seeds add texture and a gentle spice, while the celery seeds bring an earthy depth. Don’t skip the dried dill because it ties all the flavors together with that classic pickle taste.

Step-by-Step Instructions

Step 1: Prep and Process the Vegetables

Wash your radishes well and trim off the greens and root ends. Slice them thinly, then add them to your food processor along with the quartered red onion and deseeded jalapeños. Pulse until everything is finely chopped but not mushy. You want a chunky relish texture, not a puree.

Step 2: Cook the Relish Mixture

Transfer the chopped vegetables to a medium stockpot and add the vinegar, sugar, minced garlic, salt, mustard seeds, celery seeds, and dried dill. Bring everything to a boil over medium heat, stirring occasionally. Once it’s boiling, reduce the heat slightly and let it simmer for 10 to 12 minutes, stirring now and then.

Step 3: Cool and Store

Remove the pot from the heat and let the relish cool for about 10 minutes. Transfer it to a clean airtight jar and refrigerate. The relish is ready to eat right away, but it tastes even better after 24 hours when all the flavors have had time to mingle.

Pro Tips & Cooking Hacks

• Slice radishes as thin as possible so they absorb the pickling liquid properly
• Let the vinegar mixture cool slightly before jarring to prevent a mushy texture
• Double the batch and can it using a water bath method for shelf-stable jars
• Use fresh spices for the best flavor since old ones can taste flat

Tips & Variations

If you don’t have pickled jalapeños, fresh serrano or banana peppers work great. Just adjust the amount based on your heat preference. For a milder version, use mild green chilies or skip the peppers entirely.

You can swap radishes for daikon or even turnips if that’s what you have. The cooking time stays the same, and the texture will be similar. Fresh dill can replace dried dill at a ratio of about 1½ teaspoons chopped fresh to ½ teaspoon dried.

Serving Suggestions

This relish is incredible on grilled bratwurst, hamburgers, or hot dogs. It adds a bright, tangy crunch that cuts through rich meats perfectly. Spoon it over cream cheese with crackers for an easy appetizer, or stir it into tuna salad or egg salad for extra zing.

Try it on fish tacos, pulled pork sandwiches, or even as a topping for baked potatoes. The possibilities are endless once you have a jar of this stuff in your fridge.

Common Mistakes

• Cutting radishes too thick – they won’t pickle properly and will stay crunchy in the wrong way
• Pouring hot vinegar mixture directly into jars without cooling – this makes the vegetables mushy
• Using old spices – they lose potency over time and your relish will taste dull
• Not waiting at least 24 hours before serving – the flavors need time to develop

What to Serve With Radish Relish
