I love making this jalapeno relish because it adds a fresh, spicy kick to so many dishes. It’s simple to make and perfect for anyone who enjoys a little heat with their food. Scroll down to see how easy it is to whip up this tasty treat.
If you don’t usually keep jalapenos at home, you can find them in the fresh produce section of most supermarkets. They are small green peppers that add a spicy flavor. White vinegar and sugar are common pantry items, but if you don’t have them, they’re easy to find in the baking or condiment aisles.
Ingredients For Jalapeno Relish Recipe
Jalapenos: These small green peppers bring the spicy flavor that makes this relish special.
Onion: Adds a mild sweetness and crunch to balance the heat.
White vinegar: Gives the relish a tangy taste and helps preserve it.
Sugar: Adds a touch of sweetness to balance the flavors.
Salt: Enhances all the other flavors and brings everything together.
Technique Tip for Making Relish
When you’re chopping the jalapenos and onion for this relish, getting them finely chopped makes a big difference in how the flavors mix together. Here’s a simple way to chop them evenly:
- Start by cutting the onion in half from root to tip, then peel off the skin.
- Place the flat side down on your cutting board so it feels steady.
- Make several vertical cuts from the root end almost to the tip, but don’t cut all the way through.
- Then, make horizontal cuts across the onion.
- Finally, slice down across those cuts to get small, even pieces.
For the jalapenos, be careful because they can be spicy! You might want to wear gloves or wash your hands well afterward. Cut off the stem, then slice the peppers in half lengthwise and remove the seeds if you want less heat. After that, chop them finely just like the onion.
Chopping the ingredients finely helps the relish cook evenly and lets the flavors blend better when you simmer everything together. It also makes the texture nice and smooth, so it’s easier to spread on sandwiches or burgers.
When I first made this relish, I didn’t chop the peppers small enough, and some bites were way too spicy! Now, I always take a little extra time to chop carefully. Also, if you’re in a hurry, you can use a food processor for a quick chop, but just pulse it a few times so it doesn’t turn into mush.
Taking a few minutes to chop well really makes the jalapeno relish taste fresher and more balanced. It’s a small step that makes a big difference!

How to Store or Freeze Your Relish
- Ensure your jalapeno relish has cooled completely before storing. This helps maintain its texture and flavor.
- Transfer the cooled relish into an airtight container or a sterilized glass jar. This prevents any unwanted bacteria from spoiling your relish.
- Store the jar in the refrigerator. The jalapeno relish will stay fresh for up to two weeks when kept chilled.
- For longer storage, consider freezing the relish. Portion it into smaller, freezer-safe containers or use freezer bags. This allows you to thaw only what you need.
- When using freezer bags, lay them flat in the freezer. This not only saves space but also speeds up the thawing process.
- Label each container or bag with the date of preparation. This helps you keep track of its freshness.
- To thaw, move the desired portion from the freezer to the refrigerator. Allow it to thaw slowly overnight for the best texture and flavor.
- If you're in a hurry, you can also thaw the jalapeno relish in a bowl of cold water. Ensure the container or bag is sealed tightly to prevent water from seeping in.
- Once thawed, give the relish a good stir to redistribute any separated liquids and restore its consistency.
- Avoid refreezing thawed jalapeno relish. This can affect its texture and taste. Instead, use it within a few days after thawing.
How to Reheat Leftovers
Gently warm the jalapeno relish in a small saucepan over low heat. Stir occasionally to ensure even heating and to prevent sticking. This method helps maintain the relish's texture and flavor.
Microwave the relish in a microwave-safe bowl. Cover it with a microwave-safe lid or a damp paper towel to retain moisture. Heat in short intervals of 15-20 seconds, stirring in between, until it reaches your desired temperature.
If you're using the relish as a topping for hot dishes like grilled meats or tacos, simply add it directly to the hot food. The heat from the dish will naturally warm the relish without the need for separate reheating.
For a quick and easy method, place the relish in a heatproof bowl and set it over a pot of simmering water, creating a double boiler effect. Stir occasionally until warmed through. This gentle method prevents overheating and preserves the relish's vibrant flavors.
