Onion Jam

READY IN: 2hrs 20mins
Recipe by Amanda in Adelaide

I made this one up one day after looking at a couple of similar recipes. We just love this with cold meat and on sandwiches. It is like caramelised onions, only better! A food processor is really handy for this recipe.

I made this today as I had my preserving pan out for my own onion confit and chutneys! I will report back in a week, if I can wait that long, after it has mellowed a bit and award stars! It looked great, and the smell was enticing, and I cannot wait to try it next week! I took a photo before I finished bottling it, as you can see, the colour is lovely and rich due to the balsamic vinegar. As I was making lots of my own preserves, I halved the quantities. I used fresh thyme from the garden. Made for Aussie/NZ IT tag game. FT:-) FIVE stars added on the 17th September - Gorgeous - eaten with cheese on toast for tea tonight! Thanks! Mellow and just as it should be!
