Sweet Red Onion Jam

I love cooking onions and making labels. I made a batch of red onion jam today which should find its way into some tasty dishes and perhaps a burger this weekend. I used the new sweet red onions called Rubies that I just picked up. Slow cooked in Irish butter for about 2 hours, then added some brown sugar, maple syrup, and sherry and continued to cook until thick and jammy. I added some lime juice during the last few minutes to brighten it up.
