Kashering Cabinets, Drawers, & Countertops

Different opinions from different movements and rabbis

By

The following article describes various opinions regarding the kashering–making kosher-of cabinets, drawers, and countertops. When it comes to deciding which custom to follow, it is advisable, as the author notes, to discuss the matter with a rabbi. Reprinted with permission from How to Keep Kosher (HarperCollins).  

Cabinets & Drawers

Cabinets do not generally hold heated food. Therefore, they can be kashered relatively easily. Kashering basically means cleaning. Remove everything and wash the shelves and the sides. If you use shelf or drawer liners, discard the current ones and replace with new liners. Let them sit, empty, for 24 hours, then put away the food.

Countertops

Unlike cabinets, countertops do get exposed to heat. For example, if you have a heat-resistant countertop, such as wood or granite, you might put a hot pot directly on it. Or the hot ingredients inside a pot–soup, stew, hot cocoa–might spill onto it.

Countertops today are made of a myriad of materials. According to Conservative rules, all countertops are kasherable except for those made of tile, since it is earthenware.

Formica & Other “Plastics”

According to some Orthodox rulings, certain types of counters cannot be kashered. Materials that are not kasherable include the very common Formica, quartz and resin amalgamations such as Silestone, and mineral and acrylic polymer composites such as Corian. These all fall under the category of plastic, and plastic, according to some Or­thodox tenets, cannot be kashered. Some do say that Corian can be sanded down and can be kasherable in that way, but opinions vary.

Opinion is mixed as to what “not kasherable” means in terms of how to use that counter in your kosher kitchen. One Orthodox rabbi I spoke with said such counters should be covered, usually with Contact paper. Another Orthodox rabbi I spoke with said while such counters are not kasherable, it doesn’t matter; they do not need to be kashered because of how countertops are used.
