Shalom,
The media is buzzing about soy sauce (I don't know why) but in all the hoopla the fact that the inventor of the modern day soy sauce package was Jewish is explored...
http://www.aish.com/j/f/Would-Jew-Believe-40.htmlWHO NU? THE SOY SAUCE PACKET & THE JEWThe connection between Jews and Chinese food is real, and it’s deep. The connection between baggies of soy sauce packets in Jewish homes is also deep, if sometimes deeply messy. While the packet’s origin is an unsolved mystery, the story of how it became popular is known – and Jewish. That’s the story of Howard Epstein, who, as the founder of the major soy-sauce brand Kari-Out, is seen as the macher of packaged American soy sauce. Packaging is in his DNA. His father manufactured those long plastic tubey things for freezer pops. Howard, now 81, made his first foray into the biz with packaging popcorn over a half century ago. The popcorn pooped. One of his dad’s tea bag salesmen suggested he put his gelt into soy packaging which he did in 1964. While it was difficult to break into the Asian market, Epstein entered at just the right time when people were eating at home and looking for carry-out condiments, along with taking flights where food was served. Today, Kari-Out has a 50 percent market share and can even be found in Iceland. So, the next time you get a hankering for ordering in Kosher Chinese, throw a thanks to the Jew who founded your secret soy sauce stash.
