Street food from the Middle East and South Asia is defined by its sauces. The falafel, kebab or samosa is only half of the story: a spoonful of the right dip or chutney is what brings it together. Here are the ones worth learning.
Each of these sauces plays a different role. Some are cooling, such as raita and tahini. Some are sharp, such as amba and tamarind chutney. Some are fiery, such as toum and the green chutney. Serving a combination of the three is the secret of a good street-food plate.
Hummus, the smooth chickpea and tahini dip, is the starting point. It goes with falafel, grilled meat, warm flatbread and almost everything else on a mezze table.

View Recipe →Most of these keep well, which makes them ideal for batch cooking. Hummus, tahini sauce and toum keep for several days in the fridge, and the two chutneys keep for a couple of weeks. Make them on a quiet afternoon and you have the makings of a quick meal all week.
A simple way to use them: warm some flatbread, add grilled chicken or roasted vegetables, then choose one creamy sauce, one sharp sauce, and a fresh salad of tomato, cucumber and parsley. That is a proper mezze or street-food plate in ten minutes.
