Ingredients for apple cucumber relish recipe easy
Here’s what you’ll need to create this refreshing, restaurant-quality relish with minimal effort.
| Ingredient | Amount | Notes |
|---|---|---|
| Honeycrisp Apples 🍎 | 2 cups | Diced into 1/4-inch pieces |
| Persian Cucumbers 🥒 | 2 cups | Diced into 1/4-inch pieces |
| White Vinegar 🍶 | ½ cup | Distilled for best flavor |
| Granulated Sugar 🍚 | ¼ cup | Adjust to taste for sweetness |
| Fresh Dill 🌿 | ¼ cup | Finely chopped, stems removed |
| Yellow Mustard Seeds 🌶️ | 1 tsp | Toasted for extra flavor |
| Red Chili Flakes 🔥 | ½ tsp | Adjust for heat preference |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Fine grain preferred |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For moisture and richness |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
The apples and cucumbers are the stars here, so pick firm, crisp varieties—Honeycrisp apples and Persian cucumbers hold their texture best. Trader Joe’s or your local farmers market are great spots for these. Avoid any fruit or veggies with soft spots, as they’ll turn mushy in the relish. The mustard seeds and chili flakes add depth, so toast the seeds in a dry pan for 30 seconds before adding to release their aroma. Fresh dill is non-negotiable for that bright, herby flavor—dried won’t cut it here.
No Honeycrisp apples? Gala or Fuji work in a pinch, but they’ll soften faster. Substituting cucumbers? English cucumbers or Kirby cucumbers are your best bet—they’re less watery than Persian. Running low on vinegar? Apple cider vinegar gives a slightly sweeter tang, but reduce the sugar by 1 tbsp. The olive oil keeps everything moist, so don’t skip it—even if you’re watching calories. For extra crunch, add 1 tbsp of finely chopped red onion or celery.
Store this relish in an airtight container in the fridge for up to 7 days, but honestly, it’s best within the first 3 days. The flavors meld beautifully overnight, so make it the night before if you can. If you’re prepping for a crowd, double the batch—it’s that good. The ice water soak is key for texture, so don’t skip it, even if it adds a few extra minutes. Freezing isn’t recommended, as the texture suffers, but you can keep it in the fridge for a solid week.

Step-by-step instructions for apple cucumber relish
This refreshing relish comes together in minutes with simple prep and no cooking required.
Prep and Toast the Mustard Seeds
Start by dicing the 2 cups of Honeycrisp Apples and 2 cups of Persian Cucumbers into ¼-inch pieces. I like to use a sharp chef’s knife for this—cutting through the skin first makes the job easier. Place the diced vegetables in a large mixing bowl and set aside.
In a small dry skillet over medium heat, toast the 1 tsp of Yellow Mustard Seeds for 1-2 minutes until they turn a rich golden brown and become fragrant. Watch them carefully—they burn quickly. Let them cool for 30 seconds before transferring to your mixing bowl. This toasting step adds depth of flavor that raw seeds can’t match.
Combine Wet Ingredients
In a separate small bowl, whisk together the 0.5 cup of White Vinegar, 0.25 cup of Granulated Sugar, 2 tbsp of Extra-Virgin Olive Oil, and 1 tbsp of Lemon Juice. The sugar should dissolve completely, creating a smooth liquid. Taste and adjust the sweetness if needed—this is your flavor base.
Pour this mixture over the diced apples and cucumbers in your mixing bowl. Add the toasted mustard seeds, 0.5 tsp of Red Chili Flakes, and 0.5 tsp of Diamond Crystal Kosher Salt. Stir gently but thoroughly to distribute everything evenly. The relish should look vibrant with a mix of green, red, and white colors.
Fold in the Fresh Dill
Chop the 0.25 cup of Fresh Dill into small pieces, removing any tough stems. Fold the dill into the relish mixture using a silicone spatula. I like to do this in stages, mixing gently after each addition to ensure the dill distributes evenly without breaking down into a paste.
Give everything one final gentle stir. The relish should be bright, fresh, and ready to eat. The texture should be slightly crunchy with a juicy consistency—this is where the magic happens. If it seems too wet after 10 minutes, you can drain off any excess liquid, but this recipe usually balances perfectly.
Rest and Serve
Cover the bowl and let the relish rest at room temperature for at least 15 minutes before serving. This resting period allows all the flavors to meld together beautifully. The vinegar will mellow slightly, the sugar will dissolve completely, and the spices will integrate fully.
Serve immediately with sandwiches, grilled meats, or as a refreshing side dish. The relish keeps well in the refrigerator for up to 5 days, though it’s best enjoyed fresh when the vegetables are still crisp. The combination of sweet apples, crisp cucumbers, and tangy vinegar creates a perfect balance that’s both refreshing and satisfying.
Pro Tips For Making Apple Cucumber Relish Recipe Easy
- CHOP CUCS SMALL: Persian cucumbers are tender, so dice them into ¼-inch pieces—not thin slices. I learned this the hard way: thick chunks hold their shape better, and the relish won’t turn into a sad, watery mush after sitting overnight.
- USE COLD APPLES: Pull Honeycrisp apples straight from the fridge and keep them cold while prepping. Warm apples release more pectin and make the relish gummy; cold ones stay crisp and bright. (Yes, even if you’re impatient like me.)
- SALT THE DILL FIRST: Toss fresh dill with ½ teaspoon salt and let it sit for 5 minutes before adding to the relish. This softens the stems and mellows the flavor—no more chewy dill bits ruining the texture. (Your future self will thank you.)
- DILUTE THE VINEGAR: Mix equal parts vinegar and water before adding it to the relish. Straight vinegar can overwhelm the sweetness and make the apples taste harsh. A 1:1 ratio keeps the tang balanced without sacrificing brightness.

Frequently asked questions
Can I use this relish as a sandwich spread instead of a topping? This relish works beautifully as a spread when slightly thinned with a splash of water or more vinegar. For extra creaminess, stir in 1 tbsp of Greek yogurt or mayonnaise per ½ cup of relish. It pairs perfectly with roast beef, turkey, or even grilled chicken sandwiches—just
How do I keep the apples from turning brown in the relish?
Prevent browning by tossing the diced apples in 1 tbsp of lemon juice immediately after cutting and before mixing with other ingredients. The acidity slows oxidation, keeping them bright. For extra insurance, add ½ tsp of ascorbic acid (vitamin C powder) if you’re prepping ahead—it works like a natural preservative while maintaining flavor.
What’s the best way to store leftovers?
Transfer to an airtight container and refrigerate for up to 7 days. The relish actually tastes better after 24 hours as flavors meld! For longer storage, consider canning in sterilized jars (process for 10 minutes in a boiling water bath). If you notice excess liquid, drain it before storing to maintain crispness.
Can I make this relish without vinegar?
While vinegar is key for preservation and tang, you can substitute with lemon juice (use ¼ cup instead of ½ cup vinegar) or apple cider vinegar (reduce sugar by 1 tbsp). The relish will be slightly less acidic but still refreshing. For a fermented version, replace vinegar with 1 tbsp of whey and let sit 48 hours before eating—this creates probiotics!
Why did my relish turn watery?
Watery relish usually means the cucumbers released too much moisture. Drain excess liquid after 10 minutes of resting, then press the mixture gently through a fine-mesh sieve to remove water. For future batches, pat cucumbers dry with a paper towel before dicing. If the texture is still too wet, add 1 tsp of cornstarch mixed with 1 tbsp water to thicken.
