I agree that is what is needed.

In fairness, it's really hard to stock that quantity of food and be able to live on it for that long. Any recipe that contains any milk or cheese gets real tough to make when all your dairy products are a month old.

"Discipline" is a good way to phrase it. Things like learning where you can use powdered milk and where it just doesn't work out right is time consuming. Finding alternatives takes a lot of effort and trial and error.

I've been collecting pantry recipies for years and I feel like I don't have enough. I guess at some point I'll have to get those into a format that I can easily share.

Even knowing how much of various ingredients to stock is complicated. How much active dry yeast do we use a month? I couldn't tell you. Would three jars be enough for 3 months? Probably 🤷‍♂️

We plan on moving to Grocy (open source, self hosted, recipe database and inventory management system) in the near future. That will make it trivial to answer questions of what we can make with things on hand, how much of each ingredient we need to last 3 months, and so forth. It's going to be awsome once it is all set up.
