Method
- 1
Put everything in a medium saucepan and stir well.
- 2
Bring to the boil, then simmer over a low heat for 45 minutes, stirring every 5 minutes so it does not catch.
45 min - 3
When the onion is completely soft and the sauce has thickened, blend with a stick blender until very smooth.
- 4
Return to the heat and simmer for 10 more minutes, until thick enough to leave a trail when you drag a spoon through it.
10 min - 5
Taste and add a pinch more salt or sugar if you like. Pour into a clean, warm jar.
- 6
Cool, then keep in the fridge for up to 3 weeks.
