Reply To: Shmura Matzah: Hand or Machine

ItcheSrulik: thin hard matzos are MUCH more recent than “early Rishonim.” The Machatzis HaShekel (18th century) explains the Rema permits a finger’s width thick. This is thicker than soft Sefardi matzos. Also, the Rema made each matza heavier than a pound!!! Try that with thin ones.
