Ingredients
Method
- Peel the onions, then slice them thinly.
- Heat the oil in a heavy-based pad and cook the onion on a low heat until soft, stirring gently (this will take about 15 minutes).
- Add the remaining ingredients, stir, bring to a simmer then cook gently, stirring occasionally, until you get a thick, sticky jam. This will take about 35 minutes.
- Let it cool for using immediately or spoon it hot into cold sterilized jars and seal for later.
