Sweet-and-Sour Onions

• 500 g (1 lb) little button onions
• 3–4 tablespoons olive oil

Peel the onions (one way is to plunge them for a few seconds in boiling water until the skins come off easily). Sauté in oil, shaking the pan to brown them all over. Add the rest of the ingredients and a little water and cook gently till soft, adding more water if necessary.
