Since parve food is reclassified if it takes on the flavour of meat or dairy produce, Ashkenazi Jews traditionally forbid eating parve contents of a pot that has been used within 24 hours to cook meat, if the parve contents would be eaten with dairy produce. Their tradition similarly forbids eating parve foods with meat if the cooking vessel was used to cook dairy produce within the previous 24 hours. According to Joseph Caro, the Sephardic tradition was more lenient about such things,[73] but Moses Isserles argued that such leniency was unreliable.[74]
