Lucifer's Hammer

"Whole nation depends on technology. Stop the wheels for two days and you'd have riots. No place is more than two meals from a revolution.

The easy way to make beef jerky is not the way the Indians used. They employed a slow fire, or a summer sun, and their quality control was poor. Far better to set a modern oven at 100° to 120° and leave the thin strips of beef in for twenty-four hours. The meat isn't supposed to cook; it's supposed to dry. A good strip of beef jerky is bone-dry, and hard enough to kill you if you file the end to a point. It will also keep practically forever. Beef jerky is too limited a diet to keep a human being alive forever. The time can be greatly extended with vitamin supplements, but it's still dull.

The fat from the beef he pounded into pemmican, mixing it with the little sugar they had around the house, with salt, with pepper, and some Worcestershire sauce for a bit of flavor. That he'd partly cook, keeping the fat that melted out for more pemmican, and to store bacon in. Bacon covered with fat and kept protected from air will keep a long time before going rancid.
