National Pepper Pot Day is a little-known holiday observed on December 29 each year in commemoration of a dish served to the Continental Army during the brutal winter of 1777, which George Washington spent with his soldiers in Valley Forge. Supplies were scarce, and the army subsisted on a simple stew made of tripe, available vegetables, and peppercorns. The stew became a staple family meal after the war concluded, and it is often known today as “Philadelphia Pepper Pot Soup.” The following recipe is transcribed below:
After your sheep feet and belly is well clean’d and wash’d in salt and water cut the belly in small pieces, and put that and the feet in a kettle of cold water over a pretty good fire, when boiled tender put in your herbs, thyme onions parsley &cc and thicken it with a little flour, if you have any fragments mutton beef or pork, put them in, Potatoes, turnips or any other roots, add plenty of red pepper.
