Dear Deborah,
Made this..it is really good with pate too. I used Greek red onions but the result delicious !!
Best wishes from Crete.

If canned, it will keep 6 to 9 months.

Thanks Christine, I’ll look for the book! I agree, I made a double batch of the Tropea Onion Jam and still ran out too quickly!

Yes, I was going to mention Pietro Demaio’s book, too. I live in Australia, so naturally bought it here, but it’s excellent. Have just finished making Domenica’s Tropea Onion Jam from her newly purchased book, and the only thing “wrong” is that it doesn’t make enough! I didn’t use Tropea onions, of course, but supermarket red onions worked out well, so I can only imagine how good it must be to use the real thing. Will make it again soon and double the recipe. Am looking forward to trying many more recipes in the book.

Domenica, your onion jam has been a huge hit with everyone I serve it to. I need to start working through your book to try some other delicious recipes. You are welcome to visit anytime!
