I've been baking bready things for no more than 15 years, mixer or just a bowl & a stick. Pizza dough/crust, Pita, Pasta and so on.
Everybody should have a go at this. Dumb, maybe, but coming out of the oven, I am still amazed that I can do it consistently.
I'm not convinced that the line in the prayer has anything at all to do with bread.
Instead, I like to think that it's a request for all things which nourish us, each and every day.
Both the body and the spirit need feeding.
