The simplicity of good, gutsy balsamic vinegar with a little Dijon mustard for a piquant kick, this classic vinaigrette is a kitchen cupboard essential. A few, precious drops can transform salads, bring out the vim in pasta sauces and the vigour in risottos. Use it to dress tender green leaves or juicy tomatoes, drizzle over roasted vegetables or simply use as a dip for crusty ciabatta.
