Liquorice roots were imported from Spain many moon's ago and used in the manufacture of Pontefract cakes also known as Spanish button's (appro 30mm x6mm)..if you over indulged yourself getting to your Thetford in time would be a matter of good luck,if however you had a serious cough then you wouldn't need your Thetford as it would be to late..if any of you good people come across any (Spanish button's try some ,,,in moderation of course)..Kop Kops are similar tasting ..but I ain't going there 🙂🙂...Gary
