His name is Rabbi Naftali Marrus and he calls his blowtorch, “The Inferno”. The guy is serious about his work, which entails finding and scrubbing the tiniest of leavened foods (which is banned during Passover) away from kitchen counters and restaurant ovens. When he’s just about finished cleaning, he blasts the Inferno on steel trays, the inside of ovens, pots, pans and more to make sure everything’s Kosher and there’s nothing left behind.
It’s thorough work and the blowtorch can be a gnarly thing, so he always has to stay true to one of his beliefs: “you have to be respectful to the blowtorch”. I agree. Read about Rabbi Marrus and his whole Kosher Certification crew at the WSJ. [WSJ]
