Yes...I said Spamoni...not spumoni. It is however, Italian in origin as well...and as near as I can find, it's similar to a marshmallow, but I'd need a recipe to be able to compare the two.
It's often knotted in a rope form. Here is a pic of it.
If you have a recipe you are willing to share, I would appreciate it. I have many marshmallow recipes I use...but this looks even more stable. :)
