Irish pancakes are not like American pancakes. They are thinner, closer to a crepe than to a big fluffy American pancake, with no baking powder. They are typically served with honey or jam, or brushed with lemon juice and dusted with sugar.
Pancakes figure prominently in the Irish celebration of Shrove Tuesday, or Mardi Gras, which they also call Pancake Tuesday. This is the day to use up all the eggs and fat in the house to prepare for the Lenten fast. My mother's side of our family still makes pancakes on Shrove Tuesday!
