Kosher Means “Fit”
The Hebrew word kosher literally means “fit” or “proper.” In Jewish tradition, it refers to foods that are permitted for consumption, as well as to ritual objects and practices that meet Jewish legal standards. Over time, the term has entered everyday language, coming to describe anything that is honest, legitimate, or “above board.”
The laws of kashrut outline which foods Jews may eat and how those foods must be prepared. These guidelines trace back to the Torah, where the Jewish people received the mitzvot shortly after the Exodus from Egypt. Of the 613 mitzvot in Jewish tradition, roughly 30 are directly connected to food and its preparation.
Yet keeping kosher looks very different from household to household. In the United States, only about 20 percent of the Jewish population observes kosher dietary laws in some form. Many non-Jews choose kosher products because they are vegetarian, lactose intolerant, or trust the careful oversight involved in kosher certification. In that sense, ko sher has become both a deeply Jewish practice and a widely recognized symbol of thoughtful, intentional eating.
Bees Are Not Kosher, but Honey Is
According to halachah (Jewish law), products that come from non-kosher animals are generally considered non-kosher themselves. Milk from a non-kosher animal, for example, is not permitted. This raises an obvious and often-asked question: if bees are not kosher, how can honey be kosher?
The answer lies in a fascinating exception within the laws of kashrut. Honey is not actually produced by the bees’ bodies. Instead, bees collect floral nectar and carry it in their mouths and internal sacs as temporary storage. During this process, the nectar becomes concentrated as its sugar content increases, but it is not transformed into a bodily secretion. Once the nectar reaches the proper consistency, it is deposited into the honeycomb and becomes honey. Because honey originates from plants and is merely transported by the bee, Jewish law does not consider it a derivative of the insect itself. As a result, honey is fully kosher.
Mevushal Wine
Wine occupies a unique place in Jewish law and ritual, which is why its kosher status is treated differently from most other foods. While grapes themselves are naturally kosher, wine requires special handling to remain so.
According to halachah, once grapes are crushed and the winemaking process begins, the wine may be handled only by Jews who observe Shabbat. This rule was developed in ancient times to prevent wine from being used for idolatrous purposes. From crushing through fermentation, aging, and bottling, kosher wine must be produced under Jewish supervision.
When picking up a bottle of kosher wine, you may notice the terms mevushal or non-mevushal next to the kosher symbol. Mevushal literally means “cooked.” In practice, the wine undergoes flash pasteurization, a brief high-heat process applied to the grape must. This allows the wine to be handled by anyone without affecting its kosher status. It also makes serving kosher wine easier in restaurants or at events where non-Jewish staff may be present.
Different Cheeses, Different Waiting
In kosher law, moving from dairy to meat is generally simpler than the reverse. After eating most dairy products, you may eat meat immediately, provided your hands are clean and your mouth has been rinsed. This process, called kinuach (chewing to remove residue) and hadocho (rinsing), ensures that no dairy remains. If you ate with a fork and your hands never touched the cheese, a visual check is usually sufficient. If you touched the cheese directly, washing your hands is required.
Hard cheese, however, is treated differently. Hard cheeses are typically aged six months or more, or have distinctive holes, such as Swiss. Aging affects flavor and texture, allowing the taste to linger in the mouth much like meat. Because of this, hard cheeses require a waiting period before eating meat, while soft cheeses generally do not.
As always, customs vary, so it is best to consult your rabbi or kashrut authority for guidance on specific cheeses and personal practice.
Burying Pots and Pans – A Kosher Myth?
Have you ever heard the kitchen folklore that if a dish becomes non-kosher, the way to fix it is to bury it in the ground? While the idea is memorable and oddly convincing, it turns out to be a myth.
Jewish law is quite clear about how vessels are made kosher again. The Torah explains that the method depends on how the item was originally used. Utensils used over direct fire must be purified with fire, while those used with boiling liquids are kashered through immersion in boiling water. These principles are outlined explicitly in the Torah (Numbers 31:21–23) and expanded upon in great detail in the Code of Jewish Law, which devotes entire chapters to the kashering of different materials and tools.
Notably, burial is never mentioned.
So where did the story come from? One plausible explanation lies in a narrow legal case involving knives with crevices. Jewish law instructs that such a knife be pressed into hard ground repeatedly to remove trapped fat before koshering it properly. Over time, this specific instruction may have evolved into the widespread myth of burying dishes.
