#### Onion Jam Canning Recipe

Onion jam is a delightful condiment that blends the sweetness of caramelized onions with a hint of tanginess, making it perfect for pairing with cheeses, meats, or simply spreading on your favorite bread. Canning onion jam allows you to preserve this delicious treat for months, ensuring that you can enjoy its unique flavor any time of year. In this guide, we will explore the intricacies of the onion jam canning recipe, providing you with step-by-step instructions and tips for success.

#### Ingredients Needed for Onion Jam

To create a delectable onion jam, you will need the following ingredients:

- Onions: Approximately 2 pounds of yellow or sweet onions, finely sliced.

- Brown Sugar: About 1 cup, to enhance the sweetness of the onions.

- Balsamic Vinegar: 1/2 cup, for a rich, tangy flavor.

- Olive Oil: 2 tablespoons, to sauté the onions.

- Salt: 1 teaspoon, to balance the flavors.

- Black Pepper: 1/2 teaspoon, for a hint of spice.

- Thyme: Optional, fresh or dried, for added depth of flavor.

#### Preparation Steps

1. **Sauté the Onions**: In a large skillet, heat the olive oil over medium heat. Add the finely sliced onions and sauté until they become soft and translucent, approximately 15-20 minutes. Stir occasionally to prevent sticking and ensure even cooking.

2. **Caramelize the Onions**: Once the onions are soft, reduce the heat to low and continue to cook them, stirring frequently, until they turn a deep golden brown. This process can take another 20-30 minutes. Patience is key here, as caramelization enhances the flavor of the jam.

3. **Add Sugar and Vinegar**: Once the onions are caramelized, stir in the brown sugar, balsamic vinegar, salt, and black pepper. Cook the mixture over medium heat, stirring until the sugar dissolves and the mixture thickens, about 10-15 minutes.

4. **Test for Consistency**: To check if the onion jam is ready, place a small amount on a plate and let it cool for a minute. Run your finger through it; if it holds its shape, it’s ready for canning.

#### Canning Process

1. **Prepare Your Jars**: Sterilize your canning jars and lids by placing them in boiling water for 10 minutes. This step is crucial for preventing spoilage.

2. **Fill the Jars**: Using a ladle, fill each jar with the hot onion jam, leaving about 1/4 inch of headspace at the top. Wipe the rims of the jars with a clean cloth to remove any residue.

3. **Seal the Jars**: Place the sterilized lids on top of the jars and screw on the bands until they are fingertip-tight.

4. **Process the Jars**: Process the jars in a boiling water bath for 10-15 minutes to ensure they are sealed properly. The water should cover the jars by at least an inch.

5. **Cool and Store**: Remove the jars from the water bath and let them cool on a clean towel or rack. After 24 hours, check the seals. If the lid pops back when pressed, the jar is not sealed and should be refrigerated and used within a few weeks.

#### Enjoying Your Onion Jam

Once sealed and cooled, your homemade onion jam can be stored in a cool, dark place for up to a year. Use it as a topping for burgers, a spread for sandwiches, or as a gourmet addition to cheese platters. The possibilities are endless, and the unique flavor of your homemade onion jam will surely impress family and friends.
