Christopher Kimball visits Reem Kassis, author of “The Palestinian Table,” in the Galilee Valley, where he rolls bulgur maftoul by hand and enjoys a weeknight traybake made with Reem’s family spice blend. Back in the kitchen, Milk Street Cook Catherine Smart shows Chris how to make Pearl Couscous with Chicken and Chickpeas, using warm spices and flavorful chicken poaching liquid to cook the couscous. Then, Chris makes the roasted red pepper and walnut dip Muhammara, and Milk Street Cook Lynn Clark prepares a Garlicky Spiced Chicken and Potato Traybake with Pomegranate Molasses.
