"In essence, barbecuing really is the oldest form of cooking known to man," says Abboud. "It predates pots and pans and is the most elementary yet incredibly satisfying of techniques. I highly recommend you cook these skewers over hot coals because the smokiness contributes an unmistakable flavour. At Rumi, we use a reconstituted coconut shell charcoal, and the quail, in its various incarnations, has become a bit of a signature. We use onion juice to tenderise and sweeten the meat - this is an Iranian marinating technique. This pickled-grape salsa is the creation of our head chef, Jenna Abbruzzese. She hit this one spot on." Begin this recipe a day ahead to marinate the quail.
Note Pickled grapes are available from Middle Eastern grocers.
