Parsnip Potato Au Gratin

Background

Like the carrot, parsnips were cultivated in small cottage gardens starting around the 8th century.  It would not be until the very end of the 16th Century that the potato would be introduced to Ireland, most likely via Spain.  The potato did so well in Ireland, it soon became the main staple of the poor and would lead to the mass emigration due to the potato famine in the mid 1800's.
