What were typical Irish foods before the introduction of the potato?

I have always enjoyed the observation of E. Estyn Evans in his classic study, Irish Folkways (1957: "Butter spread thickly on fresh bread is a tasty if simple food, and one suspects that in pre-famine times, the staple was butter and oatcake rather than oatcake and butter. When bread was made from gritty quern-ground flour the butter would have served as a lubricant to assist the swallowing process. 'They swallow lumps of butter mixed with oatmeal', wrote Fynes Moryson around the year 1600, 'and love no meal more than sour milk curdled.' When food was left out for the fairies it was generally oatmeal and butter: needless to say, particularly when accompanied by whiskey, it disappeared during the night. In the very high present-day Irish consumption of milk products we notice once more the survival of ancient custom, for milk products were the staple food of medieval times in all parts of the British Isles." (81-81). The quote from Fynes Moryson was from his "The Manners and Customs of Ireland" (1904, p. 321)
