This is great fun. Here in Spain, we firmly believe that the first potatoes in Europe were planted in Tenerife in 1622, by Juan Bautista de Castro. Of course, it´s quite a long way from Ireland, so the two potato planters might not have been aware of each other. Even if you beat us by 34 years, we´ll still be glad to see you for holidays.

Happy St Patrick´s Day!
