In happier times in Aleppo, a sweet drink called sharab al-louz ¬– made with almond extract, milk and sugar – was a staple at celebratory events such as engagement parties and weddings, Ammar Rida recalls. That was before he had to leave his job as a lecturer at the University of Aleppo and flee Syria lest he be conscripted to fight in the war that has been ravaging his country since 2011. Today, Rida, a serious man in his late thirties with short salt-and-pepper hair and a stubbly beard, is working to establish a business selling sharab al-louz and other healthy, natural drinks – some traditional to Syria and others he is developing based on his background in food science – at restaurants in Istanbul.
