Stilton is a special type of blue cheese that can be made in only three English counties. There are just four producers of Stilton left, but this one was crowned best cheese in the world, according to one of the industry’s top awards last year. Eshe Nelson, a business reporter for The New York Times, went to Clawson Farms, the producer of the award-winning Stilton, which is trying to expand its business in the United States, despite the higher costs imposed by the Trump administration’s tariff policy.
