rekosher
v.— «Hundreds of Orthodox and Hasidic jews turned out Wednesday to have their pots, pans and silverware dipped in boiling water. It’s a process called “koshering,” which makes the materials rekosher, and is usually done on a smaller scale during Passover.…That is why, residents say, so many of them are coming down to have those plates rekoshered just in case.» —“Rush on to ‘rekosher’ after chicken scare” in Spring Valley, New York WABC-TV (New York City) Sept. 6, 2006.
