Walkers crisps are now made with 100%-British potatoes, demonstrating Walkers' commitment to quality and the British farming industry. British potatoes are of high quality, essential for the production of the nation's favourite crisps, which need to have consistent appearance, texture and flavour. To help celebrate this great British news, Walkers has brought back another great British favourite - the Worcester Sauce flavour crisp.
