The Church of the Holy Spirit Episcopal Church offers a British-style Pancake Supper on Shrove Tuesday, March 5, from 5 to 7 p.m. Shrove Tuesday is the day before Ash Wednesday; traditionally this was when Christian households used up all their stores of butter, sugar and other fatty foods in preparation for the 40 day of Lent. It is also known as Fat Tuesday or Mardi Gras.
