This topic lead me do some chazora to find a relevant statement I once filed away. The Bayur Halacha in Resh Mem Bais: opening title: vehu mikavod shabbos: ” and for this is an allusion in the scripture ‘and on the sixth day they will prepare that which they bring ( reffering to the maan) that which is baked should be baked’… inferred from here that one should bake on erev shabbos to prepare for shabbos, also in the time of the gemara this was the established custom, as brought by the Magen Avrohom. And in our great spiritual decline (ba’avotenu harabim) today ~ some women~ have abandoned this custom, and buy from a baker, and this is not proper for they lessen by this the honor of Shabbos.”
My, how the times is a’changin.
