Small onions, dark with balsamic and pleasingly sharp. Olives Et Al steep little Borettane onions in balsamic vinegar until they are crisp, dark and richly sweet, with just enough acidity to keep everything lively.

Put them beside a wedge of mature cheddar, a pork pie or a plate of salami and ham, tuck them into a roast beef sandwich, or halve them over blue cheese on toast. They are just as good with sausages, roast pork and grilled meats. Don't pour away the liquor either: a spoonful sharpens a salad dressing, deepens pan juices, or can be whisked into a little extra virgin olive oil for warm lentils and roast vegetables.
