Passover is the Brigadoon of dishes.

We only have one week a year to break our passover dishes.
If you're looking for dishes from the 1950's, 60's, 70's, advertise in Jewish publications.

It can be a problem if we buy a food processor or electric kettle to use only on passover and it breaks the second week we use it. It would be difficult to take it back to the store after a year and say we'd only used it for two weeks before it broke.
