Zesty Summer Squash Relish: A Taste of Sunshine in a Jar

I can almost smell it now: that sweet, tangy aroma wafting through my grandmother’s kitchen as she stirred a bubbling pot of summer squash. Those late June and early July days were always filled with the bounty of her garden, and this relish was her way of capturing the essence of the season. The vibrant colors and bright flavors were a welcome addition to summer cookouts, and I remember sneaking spoonfuls straight from the jar. To this day, just a hint of turmeric and the distinct fragrance of Thai basil immediately transports me back to those sunny afternoons.

Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 30 minutes
• Total Time: 1 hour
• Yields: 3 8 oz. jars
• Serves: 6-12
• Dietary Type: Vegetarian, Gluten-Free

Ingredients

• 2 cups squash, diced (1 medium large)
• 1 1/2 cups Vidalia onions, diced (1 medium to large)
• 1/2 cup bell pepper, any color, diced (1 large)
• 1/4 cup fresh ginger, grated
• 2 teaspoons salt
• 1 cup sugar
• 1 cup white vinegar
• 1 teaspoon turmeric
• 1 teaspoon celery seed
• 1/4 teaspoon nutmeg
• 1/2 teaspoon dry mustard
• 1/8 teaspoon black pepper
• 1/2 teaspoon cornstarch
• 1 cup Thai basil (finely chopped after measuring)

Equipment Needed

• Large pot or Dutch oven
• Wooden spoon or heat-resistant spatula
• Measuring cups and spoons
• Grater
• Knife and cutting board
• Jars (3 8 oz. jars) with lids and rings
• Jar lifter (optional, for hot water bath canning)
• Large pot for hot water bath (optional)

Instructions

1. Prepare your vegetables. Dice the squash, Vidalia onions, and bell pepper. Grate the fresh ginger. Finely chop the Thai basil after measuring out the 1 cup.

2. In a large pot or Dutch oven, combine the diced squash, diced Vidalia onions, diced bell pepper, grated fresh ginger, salt, sugar, white vinegar, turmeric, celery seed, nutmeg, dry mustard, and black pepper.

3. Stir all the ingredients together thoroughly to ensure even distribution.

4. Bring the mixture to a boil over medium-high heat, stirring occasionally to prevent sticking.

5. Once boiling, reduce the heat to medium-low and simmer for 20 minutes, stirring frequently. This will allow the vegetables to soften and the flavors to meld together.

6. After 20 minutes, add the chopped Thai basil and cornstarch to the pot. Stir well to incorporate. The cornstarch will help to slightly thicken the relish.

7. Continue to simmer for an additional 10 minutes, stirring constantly. This final cooking period will infuse the relish with the aromatic essence of the Thai basil.

8. While the relish simmers with the basil, prepare your jars. Sterilize them either by running them through a dishwasher cycle or by boiling them in water for 10 minutes. Keep the jars hot until ready to fill.

9. Carefully ladle the hot relish into the sterilized jars, leaving about 1/2 inch of headspace at the top.

10. Wipe the rims of the jars with a clean, damp cloth to remove any spills or residue.

11. Place the lids on the jars and screw on the rings until fingertip tight (not too tight).

12. At this point, you have two options:

    • Refrigerate the relish: Let the jars cool completely. You’ll hear a “pop” from the lids sealing. Store in the refrigerator. This method is suitable if you plan to consume the relish within a few weeks.
    • Process the relish for long-term storage: If you wish to preserve the relish for a longer period, process the filled jars in a hot water bath. Place a rack in a large pot and fill with enough water to cover the jars by at least 1 inch. Bring the water to a boil. Gently lower the jars into the boiling water using a jar lifter. Ensure the jars are not touching each other. Process for 10 minutes, adjusting for altitude if necessary (add processing time for higher altitudes).

13. After processing, carefully remove the jars from the hot water bath and place them on a towel-lined surface to cool completely. As the jars cool, you should hear a “pop” as the lids seal.

14. Once the jars are completely cool, check the seals by pressing down on the center of the lid. If the lid doesn’t flex or pop back up, it’s properly sealed. Any unsealed jars should be refrigerated and consumed within a few weeks.

Expert Tips & Tricks

• Squash Selection: While any summer squash will work, I find that a combination of yellow squash and zucchini adds visual appeal.
• Thai Basil Substitute: If you can’t find Thai basil, regular basil can be used, but it will alter the flavor slightly. Consider adding a pinch of anise seed to mimic the licorice notes of Thai basil.
• Spice Level Adjustment: Adjust the amount of black pepper and dry mustard to suit your taste preferences. For a spicier relish, add a pinch of red pepper flakes.
• Onion Caramelization: For a richer, sweeter flavor, you can caramelize the Vidalia onions before adding them to the pot. This will add a depth of flavor to the relish.
• Jar Sterilization: Proper sterilization is crucial for safe canning. Ensure that the jars and lids are thoroughly cleaned and sterilized before filling.
• Vinegar matters! Use only white vinegar with 5% acidity. Using vinegar with a lower acidity can result in spoilage.

Serving & Storage Suggestions

This Summer Squash Relish is incredibly versatile. It’s a fantastic topping for grilled hot dogs, sausages, and burgers. It can also be used as a substitute for regular pickle relish in potato salads, egg salads, and tuna salads.

For a delightful appetizer, serve it with crackers and cream cheese. The sweet and tangy flavors of the relish pair beautifully with the creamy texture of the cheese.

Storage:

• Refrigerated (unprocessed): Properly refrigerated relish (that has not been processed) will last for several weeks.
• Canned (processed): Relish that has been processed in a hot water bath can be stored in a cool, dark place (like a pantry) for at least one year.
• After Opening: Once a jar is opened, refrigerate immediately and consume within 1-2 weeks.

FAQs (Frequently Asked Questions)

Q: Can I use different types of summer squash?
A: Absolutely! Feel free to experiment with various types of summer squash, such as zucchini, crookneck squash, or pattypan squash. Each type will impart a slightly different flavor and texture to the relish.

Q: Is the hot water bath necessary?
A: If you plan to store the relish for an extended period (longer than a few weeks), the hot water bath is highly recommended. It ensures a proper seal and prevents spoilage. If you plan to consume the relish soon, refrigeration is sufficient.

Q: Can I double or triple this recipe?
A: Yes, you can easily scale this recipe up or down as needed. Just be sure to adjust the ingredient quantities accordingly. Use a larger pot if you’re making a large batch.

Q: What if my relish is too watery?
A: If the relish is too watery, you can simmer it for a longer period without the lid to allow some of the excess moisture to evaporate. You can also add a bit more cornstarch, but be careful not to add too much, as it can make the relish gummy.

Q: Can I freeze this relish?
A: While it is possible to freeze the relish, the texture of the vegetables may change slightly upon thawing. It’s best to enjoy the relish fresh or canned for optimal quality.
