I am flabbergasted that today is the first time I have heard of this.  I saw a photo a fellow posted to another venue, a grilled cheese sandwich with ham and this stuff.  He posted this link to the blog post with the sandwich recipe.  I’m going to have to revisit that place when I have a little time:)

Anyway, I saw the words “onion jam” and had to run to Google to see what this stuff was.  Plenty of variations on the caramelized onion theme, I chose a simple one:  4 yellow onions, sliced, 3 T butter, 2/3 cup brown sugar, and 1/2 cup of malt vinegar.  In a pan, heat the butter and add the onions,

cook them down until they are limp and a touch brown,

add the sugar and stir now and again until thick and caramelized,

add the vinegar and cook another few minutes.  (I swapped into a smaller, non stick, pan.)

Ta-Da!

I will be doing this again, probably with balsamic vinegar or red wine vinegar, red onions if I can find a big bag.  A fun way to while a little time away and this stuff is good enough to eat with a spoon right out of a jar.  I can see it on a hot dog, burger, cracker with goat cheese, pizza, or grilled cheese!  Mmm…
