Sometime in the mid-1400s, Rabbi Shlomo Duran of Algiers penned a remarkable teshuvah directed at a group of conversos in Spain. These individuals, who had been forced to embrace Christianity since the 1391 persecutions, had managed to maintain their Jewish faith in secrecy. Their question centered on how they could refrain from the worst forms of chametz on Pesach without drawing the suspicion of the authorities—an endeavor fraught with challenges. This teshuvah touches on many halachic elements regarding chametz and reveals the Marranos' historical struggles in mid-fifteenth-century Spain.
