National Pretzel Day is celebrated all around the country every year on April 26 since 1983. Robert S. Walker, the then representative of Pennsylvania, wanted to have a special holiday for his favorite food, pretzel, and declared this day as the National Pretzel Day. Over these 34 years the holiday has gained popularity and spread outside the state of Pennsylvania and across the country.

“Superpretzel,” the popular frozen pretzel brand, surveyed a cross-section of Americans and found some interesting pretzel eating habits:

65 percent people save the knot of a soft pretzel for the last bite while 17 percent do the contrary. Cheese is preferred as a topping by 28 percent of the sample, 17 percent opt for mustard while a mere 13 percent go for it without any toppings. Most, 69 percent prefer having a dip with their pretzel.
