With the exception of turkey on Thanksgiving and Octoberfest beer in Spetember I refuse to believe that people really like any of the holiday/season specific foods. This list includes pumpkin pie, egg nog, corned beef and cabbage, and lamb on Easter. I'm sure that other heritages have their own list. If this stuff was so good, you'd eat it year round.
On a related note how is it that an entire civilization couldn't come up with one decent dish?When's the last time you went to that really great Irish place or shopped the Irish section of the market for that final something you needed to make your favorite Irish dinner? Thank goodness for Guinness.
