        No sooner had Moscow banned dairy, meat, vegetables and fruit from most Western countries in response tosanctions over Ukraine, than Belarus, a former Soviet republic better known for black bread and potato pancakes,became a “producer” of top-quality cheese.
        Two chefs at Moscow restaurants described buying genuine Parmigiano-Reggiano, produced only in a few northernItalian provinces. It came in original Italian packaging, stuck with crude stickers saying “made in Belarus.”
        The ban on most Western food imports has been hard to swallow for those who run the pizza joints, sushi bars andFrench-style brasseries that have opened up across Russia since the fall of the Soviet Union, especially in the capitalMoscow.
        Chefs are searching for new suppliers, buying delicacies from smugglers, rewriting recipes and overhauling menus.
        Several chefs at high-end restaurants in Moscow, most of which source 85-90 percent of their produce from abroad,were convinced there’s always a way to find what they need. Belarus provides an obvious loophole. Minsk hasimposed no ban on imports from the EU and has a customs union agreement with Moscow, which means products canbe brought into Belarus legally and shipped to Russia with no border checks. Belarus has become a source not only ofItalian cheese but of fruit and vegetables, all bearing fake Belarus labels.
