 Evidence that was used to identify a crypto-Jew included the absence of chimney smoke on Saturdays (a sign the family might secretly be honoring the Sabbath) or the buying of many vegetables before Passover or the purchase of meat from a converted butcher.The court could employ physical torture to extract confessions once the guilt of the accused had been established.Crypto-Jews were allowed to confess and do penance, although those who relapsed were executed.
