I'm not sure what you would consider Jewish food, many consider it to be more European style food. A few years ago I traveled to Israel and some of you would be surprised to know that Israel is probable the most multicultural country on earth. The only other places that compared were Singapore and London. So Jewish food could basically be categorized as food from anywhere within a 5000km radius of Israel. Encompassing Ethiopia, India, Kuwait and Russia.
That being said my favorite Jewish food, on that many Israelis seem to share with me was Yemen Beef Soup. Especially with the (somehow spelt) Swhuge, a chili, garlic and coriander sambal like concoction.
