Step by step

Cook the baby onions in a pan with a little olive oil, a bay leaf and whole pepper corns

Tips
Do you want to try an unusual version - and one with a rather richer taste - of these sweet-and-sour onions? Use butter instead of oil whilst frying.
Trivia
‘Borettane’ onions originate in Emilia-Romagna, specifically in the town of Boretto, near Reggio Emilia.
