Can someone guide me on creating crafting reciepes?

This isn't a mod request, I want to learn to edit the sell lists and crafting. I want to be able to craft salted venison out of venison meat and thyme or Orgeno, both are real life curing agents, and break down cigarettes and chewing tobacco into Indian Tobacco for crafting purposes, among others. It's also be nice to be able to sell cooked and seasoned meat to butchers and general store owners.

Thing is, I've seen this work in practice with the All Items Unlocked mod, and they seem to be controlled from YMT files. But I don't know how to open them or edit them. I cannot find any sources on how to do any of this.
