But that is not the reality nowadays. Who has time to cook in bulk with a full-time job, household, garden, sports, and taking care of the kids? That immediately makes others feel guilty and start preserving dinner for the winter today...
I think that it brings you joy and has become a hobby. Some hobbies cost a lot of money; hopefully, this one even brings satisfaction, praise, recognition, and saves household money. My sister-in-law spends every free minute sewing patchwork items; compared to that, fiddling with busy boards seems more profitable and also more meaningful to me.
Back to the question of whether you need a pantry. What you call this room and where it is located in the house seems pretty irrelevant to me. However, every apartment or house should have a room where things go that need to be tidied up so you don’t drown in chaos. I have a small pantry next to the kitchen, a utility room, an attic, a basement, and soon my own study. The disadvantage of too much storage space is that you hoard, and over the years a lot of junk accumulates.
