Members of the Jewish community of Stamford Hill bring cutlery, pots, pans and dishes to kosher in boiling water in preparation for Passover. According to the Torah, as it is forbidden to eat chametz (leavened food) during Passover, utensils which have come into contact with chametz, can be immersed in boiling water (hagalat keilim) to purge them of any traces of chametz that may have accumulated during the year.
