The extent of my dedication to obeying the particular dietary rules of Passover is limited to two meals: The first seder, and a breakfast of matzah brei the next morning. I don't bother scouring the house for chametz (any bits of leavened bread, forbidden during Passover), because during the rest of the year I'm a big fan of leavened bread (it's delicious! Mmm, leavened bread) and I assume there's chametz all over my kitchen. But I wasn't aware that eradicating chametz could involve giant, high-powered blowtorches wielded by a rabbi described as being "built like a football player." Maybe I'll show more interest in the tradition next year.
