“ Pancake Day is another name for Shrove Tuesday, from the custom of eating pancakes on this day, still generally observed. A writer in the “Gentleman’s Magazine, 1790,” says, that “Shrive is an old Saxon word, of which shrove is a corruption, and signifies confession. Hence Shrove Tuesday means Confession Tuesday, on which day all the people in every parish throughout the kingdom, during the Romish times, were obliged to confess their sins, one by one, to their own parish priests, in their own parish churches ”
