What is the Hebrew word for shahbus?

There isn't a direct, single-word Hebrew translation for "shahbus" (presumably referring to a shabu-shabu hot pot). Hebrew doesn't have a single word for every culinary item from other cultures. You would need a descriptive phrase, such as:

* סיר שָׁבוּ שָׁבוּ (sir shabu shabu): This literally translates to "shabu-shabu pot" and is perfectly understandable. It's the most common and straightforward way to refer to it.

* A more descriptive phrase might be something like: סיר בישול יפני עם מרק רותח (sir bishul yipani im merek rot'ach): This translates to "Japanese cooking pot with boiling broth," which is accurate but less concise.

Therefore, סיר שָׁבוּ שָׁבוּ (sir shabu shabu) is the best and most commonly used option.
