Ingredients for Zucchini Relish

Fresh Vegetables: The Star of the Recipe

The quality of your zucchini relish starts with fresh, vibrant vegetables. Here’s what you’ll need:

Zucchini (10 cups): Choose firm, medium-sized zucchinis with unblemished skins for the best texture and flavor.
Onions (3 cups): Yellow onions are a classic choice, but white or sweet onions work well too.
Bell Peppers (4 total): Use a mix of red and green bell peppers for color and sweetness.

The Sweet and Tangy Base

This relish gets its signature flavor from a combination of sugar and vinegar, balanced with aromatic spices:

Apple Cider Vinegar (3 cups): Adds tanginess with a hint of fruitiness. White vinegar can be used as a substitute.
Sugar (3 cups): Balances the tanginess and enhances the sweetness of the vegetables. You can reduce the amount for a less sweet relish.

Flavorful Spices

A blend of spices transforms this vegetable mix into a bold and zesty condiment:

Turmeric (1 tsp): Provides a warm, earthy flavor and a beautiful golden hue.
Dry Mustard (1 tsp): Adds a subtle tanginess.
Celery Seed (1 tsp): Enhances the overall depth of flavor.
Black Pepper (1 tsp): Adds a gentle kick without overpowering the sweetness.

Optional Additions

Jalapeños or Red Pepper Flakes: For those who enjoy a spicy twist.
Chopped Garlic (1-2 cloves): Adds a savory element.
Dill Seeds (1 tsp): Introduces a fresh herbal note for a unique variation.

Preparing the Zucchini Relish

Step 1: Chopping the Vegetables

To ensure your zucchini relish has the perfect texture, chopping the vegetables evenly is essential:

Zucchini: Wash thoroughly, then trim the ends. Finely chop the zucchini into small, uniform pieces. A food processor can speed up this step, but be careful not to over-process.
Onions: Peel and finely dice the onions to match the size of the zucchini pieces.
Bell Peppers: Remove the stems, seeds, and membranes, then chop into small cubes. Use a mix of red and green peppers for a balance of sweetness and color.

Step 2: Salting the Vegetables

Salting is a crucial step that draws out excess moisture, ensuring the relish isn’t watery:

Combine the chopped zucchini, onions, and bell peppers in a large mixing bowl.
Sprinkle 5 tablespoons of salt evenly over the vegetables and toss to coat.
Cover the bowl and let the mixture sit at room temperature for 8–10 hours or overnight. This allows the salt to work its magic, improving the relish’s texture and flavor.

Step 3: Rinsing and Draining

After the salting process, it’s important to remove the excess salt:

Drain the salted vegetables in a colander and rinse thoroughly under cold running water to remove any remaining salt.
Use your hands or a clean kitchen towel to gently press out as much liquid as possible. Removing excess moisture ensures a thick, flavorful relish.

Step 4: Preparing the Spice Mix

While the vegetables drain, prepare the spice mix:

In a small bowl, combine the turmeric, dry mustard, celery seed, and black pepper.
Set the mixture aside to be added during the cooking process.

Part 4: Cooking and Canning the Zucchini Relish

Step 1: Combining the Ingredients

Now that your vegetables are prepped, it’s time to bring everything together:

In a large stockpot, add the drained vegetable mix.
Stir in 3 cups of sugar, 3 cups of apple cider vinegar, and the prepared spice mix (turmeric, dry mustard, celery seed, and black pepper).
Mix well until the sugar dissolves, and the spices are evenly distributed.

Step 2: Cooking the Relish

Cooking transforms the raw vegetables into a vibrant, tangy relish:

Place the stockpot over medium-high heat and bring the mixture to a boil. Stir occasionally to prevent sticking.
Once boiling, reduce the heat to low and let the relish simmer for 30–40 minutes. Stir frequently to ensure even cooking and prevent the mixture from scorching.
The vegetables should become tender, and the liquid will slightly thicken as it simmers.

Step 3: Sterilizing the Jars

Proper sterilization ensures your relish remains safe to eat for months:

Wash canning jars, lids, and bands in hot, soapy water.
Place the jars in a large pot of boiling water and boil for at least 10 minutes.
Remove the jars carefully using tongs and place them on a clean towel to air-dry. Keep them warm until ready to fill.

Step 4: Filling and Sealing the Jars

Using a ladle, carefully spoon the hot relish into the sterilized jars, leaving about 1/2 inch of headspace at the top.
Run a non-metallic utensil around the inside of the jar to release any trapped air bubbles.
Wipe the rims with a damp cloth to ensure a clean seal.
Place the lids on the jars and screw the bands on until fingertip-tight.

Step 5: Processing in a Water Bath

Processing the jars in a boiling-water canner ensures a proper seal and extends shelf life:

Place the filled jars in a boiling-water canner, ensuring they are fully submerged with at least 1 inch of water above the jars.
Process for 15 minutes, adjusting for altitude if necessary.
Carefully remove the jars from the canner and place them on a towel or cooling rack. Allow them to cool undisturbed for 12–24 hours.

Step 6: Checking the Seal

After cooling, check the seal of each jar:

Press the center of the lid—if it doesn’t flex, the jar is sealed correctly.
Any unsealed jars should be refrigerated and consumed within a week.

Frequently Asked Questions (FAQs)

How long does homemade zucchini relish last?

When properly canned and sealed, zucchini relish can last up to a year if stored in a cool, dark place. Once opened, it should be refrigerated and consumed within one month to maintain freshness.

Can I freeze zucchini relish instead of canning it?

Yes, zucchini relish can be frozen as an alternative to canning. Allow the relish to cool completely, then transfer it to freezer-safe containers, leaving some space for expansion. It will stay fresh for up to 6 months in the freezer. Thaw in the refrigerator before using.

Is salting the vegetables necessary?

Salting the vegetables is a critical step because it removes excess moisture, ensuring the relish doesn’t become watery. If you’re short on time, a minimum of 2–3 hours of salting can work, but overnight is recommended for the best results.

Can I use other types of squash instead of zucchini?

Absolutely! Yellow squash, pattypan squash, or a mix of summer squash varieties can replace zucchini in this recipe. The flavor and texture will remain similar, though the color may vary.

How can I reduce the sugar content in zucchini relish?

To make a less sweet relish, reduce the sugar by half or substitute it with a natural sweetener like stevia or monk fruit. Adjust the vinegar slightly to balance the tanginess.

What’s the best way to ensure a proper seal during canning?

To achieve a perfect seal, sterilize your jars and lids before use, and process them in a boiling water bath for the recommended time (usually 15 minutes). After cooling, check that the lid doesn’t flex when pressed—this indicates a proper seal.

Can zucchini relish be made spicy?

Yes, you can easily add heat to your relish by including jalapeños, red chili flakes, or cayenne pepper in the recipe. Adjust the amount to suit your spice tolerance.
