Creamy Potato, Leek and Stilton Soup

A velvety British soup combining soft leeks and potatoes with the distinctive blue cheese tang of Stilton. Butter-sautéed leeks form the aromatic base, simmered with floury potatoes until tender, then blended smooth with single cream and crumbled Stilton for a rich, savory finish. Topped with extra cheese and pepper.
