Personally, as with a lot of the comments, I’m in the food-prep and make it yourself crowd.

I found a book that dives into the details of when it is and isn’t worth making things from scratch.

It’s called Make the Bread, Buy the Butter.

Honestly, I haven’t read it yet. I bought it and let my mom borrow it immediately, but when I get it back I think it will an interesting read.
