Halve and pit the plums then cut into quarters. Cut the onion into wedges and mix with the plums. Divide between your jars
Put the rest of the ingredients into a saucepan. Bring to the boil until the sugar dissolves
Pour the hot liquid over the plums and onion in the jars
Let cool uncovered then put on the lids and refrigerate for at least 8 hours
Will keep refrigerated for a week
Enjoy as you would chutney or salsa, as a side or as a dip. Goes great with pork and grilled meats
This makes lot to use within a week so adjust as you need to, I like to give the extra to my parents, sister & neighbours. I've set the serving size as 4 for 4 x 300 jars so you can adjust the amount of servings by the number of jars you want to make
