A Walnut Whip is a whirl-shaped cone of milk chocolate with a whipped vanilla fondant filling, topped with a half-walnut.Launched in 1910 by Duncan's of Edinburgh, Walnut Whip is Nestlé Rowntree's oldest current brand. Over one million walnuts, most of them imported from China and India, are used every week in the manufacture of Walnut Whips at Halifax, West Yorkshire. Nestlé claim that a Walnut Whip is eaten almost every two seconds in the UK.There have been a number of flavours of Walnut Whip over the years, including coffee and maple flavours, but currently only vanilla is widely available. The original Walnut Whip contained a half-walnut placed inside the cone on the thick chocolate base, rather than on top. It was later marketed with an extra walnut on top, and subsequently the walnut inside was removed to leave one walnut outside.
