The primary ingredient in a traditional currant scone is flour, typically self-rising or all-purpose flour. Flour provides the structure and base for the scone, while currants are added to provide sweetness and texture. Other common ingredients include baking powder, sugar, butter, milk (or cream), and sometimes eggs. The mixture is combined to create a soft dough that is then shaped and baked until golden brown. Traditional currant scones are often served with clotted cream and jam as part of a tea service, making them a beloved treat in British culture.
