Sumac
A spice that is becoming hugely popular in the UK thanks to Ottolenghi et al. This dark red burgundy spice is most commonly used in Middle Eastern cuisines where it is used as an all purpose seasoning or for sprinkling on salads and rice.
With its lovely tangy, citrusy flavour, sumac also makes an excellent rub for grilled meats and especially fish, or it is delicious when mixed with yoghurt and other spices such as chilli, cumin or coriander to make simple marinades & dressings. For something a little different, try adding a dash to the top of hummous for a new taste. You can also use a sprinkling of this pretty purple spice as a garnish in the same way paprika is sometimes used. Try it in salads or sprinkled over buttery rice.
