Quick answer: Caramelised onion jam is made by slowly cooking onions until soft and golden, then adding sugar and vinegar and reducing to a thick, spreadable relish. Coconut sugar works well because its caramel notes deepen the cooked onion flavour. Add it after the onions have softened, balance it with vinegar and cook until glossy.
Key takeaways – Coconut sugar deepens the caramel flavour of onions. – Add sugar after onions soften. – Balance sweetness with vinegar and salt. – Producers must validate jarring and shelf life.
What makes onion jam special
Onion jam combines sweet, sour and savoury flavours. It is popular on cheese boards, burgers, sandwiches and with roasted meats or vegetables. The long cooking of the onions creates natural sweetness, and the added sugar and vinegar turn it into a preserve.
Basic method
- Slice onions thinly.
- Cook slowly in oil or butter until soft and golden.
- Add coconut sugar and stir until dissolved.
- Add vinegar, salt and optional herbs.
- Simmer until thick and glossy.
- Cool and store, or jar using a validated process.
Choosing the vinegar
| Vinegar | Flavour effect |
|---|---|
| Balsamic-style | Rich, dark, sweet |
| Red wine vinegar | Fruity, sharp |
| Apple cider vinegar | Mild, fruity |
| Sherry-style vinegar | Nutty |
Balancing flavour
Taste near the end of cooking. If it is too sweet, add a little vinegar or salt. If too sharp, add a little more coconut sugar. Herbs like thyme or rosemary add aroma.
Colour
Coconut sugar adds to the deep brown colour that onion jam already develops. It fits the product’s natural look.
For food producers
Commercial onion jam needs controlled acidity, sugar content and heat treatment for safety and shelf life. Work with a food technologist to set pH and Brix targets and validate the process. Label all ingredients and allergens.
Uses
- Cheese boards and charcuterie.
- Burgers and sandwiches.
- Tarts and savoury pastries.
- Glaze for roasted vegetables.
- Side for grilled tofu or meats.
Batch consistency
Onions vary in sweetness and water content by variety and season. Weigh onions and sugar, record cooking times and check the final thickness. A refractometer reading at the end helps make each batch similar.
Gift and retail packs
Onion jam is popular in gift hampers and delicatessens. Small jars with clear labels showing ingredients, including coconut sugar, appeal to shoppers looking for something different. Check label rules in each market before launch.
