A 'Belgian bun' is an iced bun, covered with
raisins and usually topped with half a glazed cherry. The bun is square shaped, with rounded off edges, making it similar in appearance to a
Chelsea bun. No firm link has so far been established between the bun and
Belgium; however, that country does produce as one of its specialities a very similar pastry (though with less icing) known as a ''couque suisse''.
