Explaining kosher certification to non-Jewish customers

Posted on: May 24th, 2023 by Kosher Michigan

By Jonathan Deutsch, Ph.D.

How do I explain kosher certification to non-Jewish customers? I own and operate a kosher restaurant. Operating a kosher restaurant is extremely challenging because we have to make sure that every morsel of food that comes into the restaurant is kosher. Recently, a customer pointed out to me that another family was feeding their baby food that was not from the restaurant. I approached the guests and politely told them about our outside food policy, and requested they put the food away to eat later.

Kosher establishments that appeal to both Jews and non-Jews face particular challenges. A restaurant can lose its certification not just by flouting religious law, but based on the behavior of employees and guests with regard to the law, as you experienced. The importance of obeying the rules to maintain certification cannot be overstated.

If there is a theme to this column over the years it is that clear communication can prevent many problems before they occur. At this point, after explaining the situation to the guest, there’s nothing more to do besides focusing on preventing similar misunderstandings in the future. Rachel Saks, cofounder of TableHealth and author of Jewish American Food Culture says, “I think that there are a few ways to approach it. If it’s a casual place…it would be good to hang up signs that say something like, ‘Because of the dietary laws we adhere to as a kosher business, please refrain from bringing in your own food and drinks.’ I also think that if it becomes an issue with a particular person, as in this case, its best to approach them assuming that they know very little about kashrut [kosher law], while also not talking down to them…I think it’s important to say something like, ‘Because of our religious observances all of our food needs to be checked and watched. The restaurant is a sectioned-off space in which all food that goes in and out and all food that is prepared needs to be checked for certain standards. No one, even the people who make sure our food is held to the proper kashrut standard, may bring in food. If you have questions about what it means for food to be kosher, or how we ensure that our establishment stays kosher, I’m happy to answer them.’”

In addition, try some FAQs targeting non-Jewish guests on your menu. The guests’ dissatisfaction may have as much to do with the embarrassment of not knowing the rules and being called out on it, more than any specific service failure on your part.

To whom it may concern:

Rabbi_Steven_Rubenstein_MichiganOn behalf of the Michigan Region of the Rabbinical Assembly, I am writing to voice our support for Tamarack Camps and its dedication to kashrut for its camps.

As executive director, Jonah Geller has worked energetically during his tenure to maintain the kashrut of Tamarack and to enhance the Judaic spirit of camp. We believe that the recent hiring of Rabbi Jason Miller as Rav HaMakhshir for camp is an expression for the camp’s dedication to kashrut for Camp Tamarack. Rabbi Miller’s experience and dedication to the laws and standards of kashrut will ensure that the high standards of kashrut that have been present at the camp in the past will continue. Rabbi Miller’s past experience as a mashgiah at the Jewish Theological Seminary and his planned study with Rabbi Joel Roth give Rabbi Miller the proper background for this work. We are pleased that Rabbi Miller also plans to take part in the Rav HaMakhshir program of the Rabbinical Assembly to increase his knowledge and skills in regard to serving in this position.

Tamarack has made a positive and important statement about its dedication to kashrut in its hiring of Rabbi Miller. We wish Tamarack Camps much success in its continued mission of providing Jewish camping opportunities to the children and families of greater Detroit.

The Michigan Region of the Rabbinical Assembly looks forward to working with Tamarack Camps for many years to come.
