Observant Jews have separate sets of dishes, and sometimes different kitchens, for meat and milk, and wait anywhere between one and six hours after eating meat before consuming milk products.<ref>''Shulchan Aruch'', ''Yoreh De'ah'' 87 ''et seq''</ref> The {{transliteration|yi|milchig}} and {{transliteration|yi|fleishig}} (literally "milky" and "meaty") utensils and dishes are the commonly referred-to Yiddish delineations between dairy and meat ones, respectively.<ref>{{cite encyclopedia|url=https://www.jewishvirtuallibrary.org/jsource/Judaism/kashrut.html|title=Kashrut: Jewish Dietary Laws|encyclopedia=[[Jewish Virtual Library]]|access-date=May 22, 2013}}</ref>

According to the Shulchan Aruch, a six-hour waiting period is recommended between consuming meat and dairy. During this time, it is generally advised to abstain from brushing and rinsing the mouth.<ref>A halachic answer on the topic of [https://meshiv.co.il/en/shelot_vetshuvot/after-eating-meat-can-i-use-dental-floss-and-rinsing-my-mouth-and-eat-milk-with-out-waiting-6-hours/ after eating meat, can I use dental floss, and rinsing my mouth, and eat milk without waiting 6 hours] on the website [https://meshiv.co.il/en/home-page1/ "Meshiv Kahlahah"].</ref>

[[Shelomo Dov Goitein]] writes, "the dichotomy of the kitchen into a meat and a milk section, so basic in an observant Jewish household, is [...] never mentioned in the [[Cairo Geniza|Geniza]]." Goitein believed that in the early Middle Ages Jewish families kept only one set of cutlery and cooking ware.<ref>Goitein, Shelomo Dov. ''A Mediterranean Society: The Jewish Communities of the Arab World as Portrayed in the Documents of the Cairo Geniza, Vol. IV. p. 252''. {{ISBN|978-0-520-22161-1}}.</ref> According to [[David C. Kraemer]], the practice of keeping separate sets of dishes developed only in the late 14th and 15th centuries.<ref>Kraemer, David C. (2007). ''Jewish Eating and Identity Through the Ages''. New York: Routledge. pp. 99–121. {{ISBN|978-0-415-47640-9}}.</ref> It is possible observant Jews before then waited overnight for the meat or dairy gravy absorbed in a pot's walls to become insignificant ([[:he:נותן טעם לפגם#נותן טעם לפגם בכלים|{{transliteration|he|lifgam}}]]) before using the pot for the other foodstuff (meat or dairy).<ref>{{cite web|date=2016|title=The Development of a Waiting Period Between Meat and Dairy: 9th – 14th Centuries|url=http://www.oqimta.org.il/oqimta/5776/adams4.pdf|website=Oqimta: Studies in Talmudic and Rabbinic Literature. 4: 79-84, note 222}}</ref>
