Bread sauce is a traditional British accompaniment to roast chicken and turkey, made by infusing milk with onion and cloves, then thickening it with fresh white breadcrumbs and enriching it with butter. The mixture is gently heated until the crumbs swell and the sauce turns smooth and creamy, then seasoned with salt, pepper, and nutmeg. It is served hot alongside the roast, where its mild, comforting flavour balances rich gravies and stuffings. Dating back centuries as a way to use stale bread, it remains a fixture of Christmas and Sunday roast dinners, illustrating how frugality shaped classic cuisine.
