Pretzels date back almost 14 centuries to an Italian monk, who, while baking bread for Lent, twisted a roll of dough to resemble the sign of the cross. To genuflect or make the sign of the cross is a prayer posture of Catholic Christians. Pretzels have become a traditional Lenten fasting food as they are made without sugar, fat, meat or dairy. In traditional Catholic homes, all fat, dairy and sweeteners are used up on Shrove Tuesday (also called Mardi Gras or Fat Tuesday) in anticipation of the "vegan" Ash Wednesday and the beginning of Lenten fasting. Shrove Tuesday is also sometimes called Pancake Day because these ingredients were made into pancakes for the pre Lenten Mardi Gras feast. During Lent, Catholic Christians observe meatless Lenten fasting on Fridays. They may refrain from eating fats, oil, butter, sugar, sweets and dairy products as a spiritual Lenten fasting.
