My family’s minhag (Yekkish – Hamburg) is not to eat matza from after Purim. I have never seen a mekor for this. Does anyone know where it comes from? But it’s only proper matza. Matza crackers and matza meal is fine up to and including erev pesach.
I have been known to eat shalosh seudos with matza until erev pesach. -pleeease don’t tell my father.
