Ingredients
Scale
Ingredients
- 4 large Sweet Yellow Onions (Vidalia or Maui onions recommended)
- 2 tablespoons Extra-Virgin Olive Oil
- 1 cup Granulated Sugar
- 1/4 cup Balsamic Vinegar
- 1 teaspoon Sea Salt
- 1/2 teaspoon Ground Black Pepper
- Fresh or Dried Herbs (e.g., Summer Savory) (optional, to taste)
Instructions
- Prepare the onions: Peel and thinly slice 4 large sweet yellow onions. Use Vidalia or Maui onions if available for optimal sweetness and texture.
- Sauté the onions: Heat 2 tablespoons of extra-virgin olive oil in a heavy-bottomed saucepan over medium heat. Add the sliced onions and cook, stirring occasionally, until they start to soften and become golden, approximately 10-15 minutes.
- Caramelize slowly: Reduce the heat to medium-low. Continue cooking the onions for about 45 minutes, stirring regularly to prevent burning, until they turn a deep golden-brown color and have a rich caramelized aroma.
- Add sugar and vinegar: Sprinkle in 1 cup of granulated sugar over the caramelized onions and carefully drizzle 1/4 cup balsamic vinegar to avoid splattering. Stir frequently and cook the mixture until it thickens and becomes syrupy.
- Season the jam: Add 1 teaspoon sea salt, 1/2 teaspoon ground black pepper, and any desired fresh or dried herbs such as summer savory. Mix thoroughly and adjust the seasoning to your taste.
- Jar and store: Ladle the hot onion jam into sterilized jars, leaving some headspace. Seal the jars tightly and allow them to cool completely at room temperature before storing in the refrigerator. The jam will keep well for several weeks.
Notes
- Use sweet yellow onions like Vidalia or Maui for the best natural sweetness and flavor.
- Stir the onions frequently during the long caramelization process to avoid burning and ensure even cooking.
- Add sugar only after the onions are fully caramelized to enhance a sticky, jam-like texture.
- Carefully add balsamic vinegar to prevent hot splatter and burns.
- Customize the flavor with fresh or dried herbs such as summer savory, thyme, or rosemary.
- Store the jam in sterilized jars and refrigerate; it can last up to 3 weeks refrigerated.
