1.5kg onions (red onions work very well), chopped
1kg sugar
500ml red wine vinegar
a sprinkle of salt
2-3 teaspoons caraway seeds
- sprinkle the onions with a little salt in a large bowl. set aside.
- in a heavy based pan, add sugar, vinegar and caraway seeds. boil for 5 minutes.
- add the onions - i don't bother to wash off the salt - and cook on a low heat for at least 2 hours. sometimes i leave it on the low heat for about 4 hours, until it no longer tastes overly vinegary and has thickened.
- put into sterilised jars. as soon as it is cool you can eat it. yummy!
- keep opened jars in the fridge, unopened ones in a dark cupboard.
