What constitutes a condiment (Idam) when one swears an oath not to eat condiments?

Primary text

If a person swears an oath not to eat condiments (Adum), they break their oath by consuming anything customarily eaten with bread. This includes liquids used for dipping, such as cooked foods, broth, vinegar, oil, ghee, sesame oil, and milk. Evidence for this includes Allah's statement regarding oil: "and oil, a source of light for those who eat" (Quran 23:20). Furthermore, the Prophet, peace be upon him, stated, "Excellent is vinegar as a condiment," and commanded, "Eat oil and apply it, for it is from a blessed tree," as narrated by Ibn Majah. It also includes solids such as roasted meat (shawaa), cheese, broad beans, olives, and eggs. This view is held by Al-Shafi'i and Abu Thawr.
