OK, so “How To Can Anything” or “Food In A Jar” has all the canning recipes, and several books have various recipes for other things.
Again, the issue is that recipes from books are not always written out in cookbook format. Rather, they represent the ability to take an idea from the book and actually make it happen.
Cookbooks are written to be easy to understand and reproduce the result: therefore, it’s usually pretty easy to find and use the recipe (low skill requirement for it to show up in crafting). Survival Under Atomic Attack is poorly written, though, so whilst there’s a pile of useful recipes in there, they all take above-usual skill in the topic to realize “hey, I could do X, Y, and Z and make T!”.
Thus, not every book has to have all the canning recipes just because it contains one. If a book contains the recipe for woods soup, it can probably contain the recipe for canned woods soup, without regard to whether it contains a recipe for canned veggy. The PC would realize that the soup could be cooked and sealed in a jar for later.
