These lovely and aromatic little onions can be served hot or cold, as an antipasto or side vegetable.
I should have used little Italian flat onions, like the borrettane, but they don't sell them in NZ so I used some normal pickling onions. Peel the onions, soak in water for two hours, drain and then cook very slowly with a dollop of salted butter, a few fresh sage leaves and a pinch of salt for a long long time. I cooked them in a Le Creuset pot, with the lid on, stirring often. Check to see if you need to add just a little water half way through, but personally I didn't need it, mostly they cooked in their own steam (Le Creuset pots have great lids!!) and they caramelized a little too, becoming sweet and fragrant. All in all they took about 2 hours. Once they were cooked I turned the element off and added a drizzle of Aceto Balsamico Tradizionale di Modena Extra Vecchio (25 year old), covered them again with the lid, and let them rest for 20-30 minutes before serving.
Popular variations include adding cloves, or grilling the onions instead of simmering them (obviously the flat onions are easier to grill than the round pickling onions!).
