Cipolline in agrodolce

Method

1. 1 Blanch the small onions in boiling water for 2 minutes, then peel them. This method is very quick and prevents the onions from becoming mushy.
2. 2 Melt the butter with olive oil, then add the onions and sauté until golden brown on all sides.
3. 3 Sprinkle sugar over the onions and stir until the sugar dissolves and caramelizes around them.
4. 4 Pour in the wine vinegar, add the bay leaves, then cover and simmer over low heat for 20 minutes.
5. 5 Open the lid and simmer until the sauce thickens into a glossy syrup, then let it cool before serving.

With an appliance

  Replace step 4: loosely cover the bowl of onions with vinegar and bay leaves, and microwave at 700 W for 8 minutes; step 5 continues to simmer in the pan for 5 minutes until the sauce thickens like syrup.
