Christopher Kimball travels to the Galilee Valley to make a kafta traybake with Reem Kassis, author of “The Palestinian Table.” Then, Chris heads to Tel Aviv for a meal at Shlomo & Doron, a shop famous for its hummus, both classic and unconventional. Back in the kitchen, Chris makes Lebanese Baked Kafta with Potatoes and Tomatoes, a comforting casserole with warm spices, followed by Hummus with Chipotle Black Beans and Tomato Salsa. Finally, Milk Street Cook Lynn Clark bakes soft and chewy Yeasted Flatbreads with Za’atar Oil.
