Hoosh is a stew made of pemmican*, crushed biscuit, and what fresh meat as can be caught, all mixed and heated through with water.
In a pinch, hoosh is just pemmican and boiled water.
In an even tighter pinch, serve it up DIY-style by just chewing on the pemmican cubes.
*Pemmican: drief beef pounded to a powder, mixed with suet or fat; sometimes including dried fruit as well.
