What is a campfire grubstake?

A campfire grubstake is a term used in camping and outdoor cooking to refer to a supply of food and provisions that are taken along to be cooked over a campfire. It typically includes basic ingredients like flour, sugar, salt, pepper, and cooking oil, along with other foods that can be easily cooked over an open fire, such as bacon, sausage, beans, potatoes, and canned goods. The term "grubstake" originates from the American Old West, where prospectors and miners would receive their supplies from a grubstake, which was essentially a loan of food and equipment provided by an investor in exchange for a share of any profits.
