Reply to comment by dbx999 in TIL of Portable Soup, also known as pocket soup or veal glue. A precursor of meat extract, bouillon cubes, and of industrially dehydrated and instant food, it is essentially a partially dehydrated broth and a solid counterpart of meat glaze. by IPeeFreely01

It was used for flavor, not nutrition. Pocket soup would be added to whatever stew you were making, similar to how we use bouillon.
