Close to McVitie's Digestive Biscuits on BigOven: "Traditional British biscuits, digestives can also be served buttered or with cheese. For a sweeter biscuit, brush one side with melted semisweet chocolate after baking."
McVities Digestives - I fell in love with these biscuits in the Netherlands, then I was able to feast on them in Finland one year later. Finally these British biscuits are also available in Gemany. Awesome!
