It is said that no country drinks more tea, per capita, than Ireland. Americans are known for leaving a pot of coffee on all day long, but the Irish are known for doing that with tea. They like their tea strong. It is said they like it so strong that a fork will stand up in it.
I haven't tested this theory, of course.
The Irish also like milk with their tea, a practice I am not a fan of. They add the milk first, sometimes as much as filling half the cup.
Tea came to Ireland around the 19th century, and was reserved for special guests. This, mostly, because tea was expensive. It did eventually make its way into the rural areas.
So, today, in honor of St. Patrick, have some tea. Green tea, if you are feeling festive, Irish Breakfast if you want to be more traditional.
