Many of you know that Sephardic Jews eat corn, beans and rice on Pesach, while Ashkenazic Jews do not. The removal of hametz is accomplished through a general cleaning, of all rooms of the house, not just the kitchen. It may take time to accomplish. The final bread, when found, is scooped up with a feather into a wooden spoon, and then ritually burned. A formula declaring all hametz that the family did not find to be null and void is then recited.
Some people resist ritual, or scoff at ancient rules.
But the ritual is there for a reason. There is a message behind this mad rush of cleaning. Removing the Hametz by Rabbi Lynn Gottleib Removing the Hametz in the month of Nisan with the death of winter and the coming of spring our ancient mothers cleaned out their houses. They opened windows to the sun hung lines for the airing out of blankets and covers using fire air and water in the cleaning. In the month of nisan before the parting seas called them out of the old life our ancient mothers went down to the river they went down to the river to prepare their garments for the spring.
