I think the infomercial apes who hawk these things would probably disagree that this only makes one thing. As far as they're concerned, these pups are like a magical chef, preparing delights from tasty chipped beef to delicious apricot chews. But from my point of view, jerky is jerky. Thus you get beef jerky, turkey jerky, apple jerky, plantain jerky, what have you. There's a reason jerky typically comes in half-ounce packets.
Nobody needs extra jerky.
These are great for teaching children about the lack of reward for hard work. If you churn, it's not worth it. If you deposit it in the freezer, it's not really hand-crafted. Either way it's more expensive than the store brand and less tasty than Ben and Jerry's. An elegant solution to a thorny and chronic problem.
