<prompt> Human: I already cook just about all of my meals, but not from scratch. I typically start with boxed pasta, chopped frozen veggies, canned beans, sliced bread, etc. Id happily make a lot of these things from scratch, especially the bread and pasta, if theres a cost savings involved.So, Im wondering if any of you have opinions on what foods it makes sense to do this for, when the time investment is included. I do love being in the kitchen and this could be a great hobby for me, but that doesnt mean I dont also have more pressing things to deal with in my down time.  <response>: For most staples youll never approach the economies of scale costs of a modern suppliers, like pasta, rice, and beans, takes a long time to grow and prepare.
