Zucchini and Onion Relish Recipe

Ingredients with Measurements:
- 4 medium zucchinis, diced
- 2 medium onions, diced
- 1 red bell pepper, diced
- 1 green bell pepper, diced
- 1 cup white vinegar
- 1 cup granulated sugar
- 1 tablespoon mustard seeds
- 1 tablespoon celery seeds
- 1 teaspoon salt
- 1/2 teaspoon ground black pepper

Special equipment needed:
- Large pot
- Canning jars with lids and bands

Step-by-step instructions:

1. In a large pot, combine the diced zucchinis, onions, red and green bell peppers, white vinegar, sugar, mustard seeds, celery seeds, salt, and black pepper.

2. Bring the mixture to a boil over medium-high heat, stirring occasionally.

3. Reduce the heat to low and simmer the mixture for 30-40 minutes, or until the vegetables are tender and the liquid has thickened.

4. While the relish is simmering, prepare the canning jars by sterilizing them in boiling water for 10 minutes.

5. Once the relish is done, ladle it into the sterilized jars, leaving 1/2 inch of headspace at the top.

6. Wipe the rims of the jars clean with a damp cloth, then place the lids and bands on top.

7. Process the jars in a boiling water bath for 10 minutes.

8. Remove the jars from the water bath and let them cool on a wire rack.

9. Once the jars are cool, check the seals by pressing down on the center of the lids. If the lids do not pop back up, the jars are sealed properly and can be stored in a cool, dark place for up to one year.
