Some of the world’s best-loved (and most easily made) dips have surprisingly few ingredients. From a Middle Eastern-style hummus to Mexican guacamole and a French tapenade, you can go globe-trotting from your kitchen in a flash. Each of our simple recipes needs just three ingredients, a little salt and pepper, and can easily be jazzed up with fresh herbs for flavour and colour, a squeeze of lemon or lime or a dash of hot chilli.
