But they did back in the day.
If it is a skill that is being lost, that to me says we should be teaching it to people, not making it a posh thing that only people above a certain income bracket can afford to buy when made by someone else.
I mean all of my grandparents knew how to make bread, I bet most other people around the same age their grandparents or parents made bread, and some of us might have been lucky enough to have someone teach us how to do it. Most people can actually do it.
It has switched from being a basic survival skill to "artisan" - no it's not artisan to be able to make a loaf. If someone is making oh I don't know, stained glass, or jewellery, or pottery, that is artisan.
Making a loaf of bread is basic baking, not a specialist subject with specialist craft skills. We need to stop mystifying it, and maybe remind people how to make bread like everyone has done for centuries.
