AI-Generated Summary (AI can be inaccurate. Check important information): 1. *Cooking doesn't undo identity* — While *halacha* normally maintains that cooking a vegetable does not change its essential status (remaining *Borei Peri Ha’adama*), a special dispute exists regarding whether cooking can undo a previous state of roasting or baking. 2. *Matzah and Korban Pesach distinction* — The *Gemara* in *Berachos* suggests that cooked *matzah* is invalid only because of a specific requirement for *ta'am matzah* (the taste of *matzah*), whereas the *Gemara* in *Pesachim* uses the same case to suggest a general principle that cooking (*bishul*) overrides roasting (*tzli*). 3. *General status vs. process* — The *Eglei Tal* resolves contradictions between the *sugyos* by distinguishing between a food's essential identity (a vegetable remains a vegetable) and the physical process it underwent (cooking can replace baking or roasting). 4. *Shabbos as an exception* — The *Taz* suggests that *Hilchos Shabbos* may be stricter than other areas of *halacha*; even if cooking doesn't legally "undo" baking elsewhere, on *Shabbos*, adding or changing flavor through heat constitutes an act of *bishul*. 5. *Practical application for reheating* — There is a significant *machlokes* regarding whether one may place baked *challah* on a *platta* (roasting after baking) or put cooked chicken on a *platta* (roasting after cooking), with many being *meikel* (lenient) based on the *Magen Avraham* and *Shiltei Gibborim*. 6. *Bread in soup bowls* — Although we are generally *machmir* (stringent) not to put baked bread even into a *kli sheni* (secondary vessel), the *Mishna Berurah* permits putting bread into a soup bowl if the soup was moved via a ladle, effectively treating the bowl as a *kli shlishi* (tertiary vessel) in the context of this specific stringency.
