Ka'ak (Arabic: كعك, also transliterated kaak) or Kahqa is the Arabic word for "cake", and can refer to several different types of baked goods produced throughout the Arab world and the Near East.
Ka'ak can refer to a bread commonly consumed throughout the Near East that is made in a large ring-shape and is covered with sesame seeds. Fermented chickpeas (known as hummus in Arabic) are used as a leavening agent. Widely sold by street vendors, it is usually eaten as a snack or for breakfast with za'atar. In East Jerusalem, it's sometimes served alongside oven-baked eggs and falafel.Palestinians from Hebron to Jenin consider Jerusalem ka'ak to be a unique specialty good, and those from the city or visiting there often buy several loaves to give to others outside the city as a gift.
In Lebanon, ka'ak bread rings are made of sweet dough rolled into ropes and formed into rings and topped with sesame seeds. Instead of za'atar, after baking, it is glazed with milk and sugar and then dried.Tunisian Jews also make a slightly sweet-and-salty version of the pastry, but don't use a yeast-based dough. In Egypt, usually at wedding parties, a variation made with almonds, known as kahk bi loz, is served.
A thirteenth-century Middle Eastern culinary text,Kitab al Wusla il al Habib, features three recipes of ka'ak.
The pastries or sweets known as ka'ak are semolina-based cookies such as ka'ak bi ma'moul (or ka'ak bi ajwa) which is stuffed with ground dates, ka'ak bi jowz which is stuffed with ground walnuts and ka'ak bi fustok which is stuffed with ground pistachios.
