Step-by-Step Instructions for Simple Caramelized Onion Jam
- Begin by filling a canning pot with water and bringing it to a boil. Gather and clean your canning jars.
- In a heavy-bottomed pan, heat the olive oil over medium heat. Add the sliced onions, stirring occasionally. Cook for 10-15 minutes until golden brown.
- Stir in the granulated sugar and balsamic vinegar. Continue cooking over medium heat for about 45 minutes, stirring regularly until thick and syrupy.
- Add a pinch of salt, ground black pepper, and summer savory during the last 10 minutes of cooking. Stir well to combine.
- Pour the hot jam into prepared jars, seal with lids, and process in boiling water for 10 minutes.
- Let the jars cool at room temperature for 24 hours. Check seals and store in a cool, dark place.

Notes
Patience is key for ideal texture; add granulated sugar after onions are caramelized. Stir frequently to avoid sticking, and check jar seals after cooling.
