* For solid food, 39 Melachos (vol 2 pg 553) writes that the Biblical prohibition is only violated when the food is changed from being inedible to edible. There is a dispute in the Rishonim about what is considered a minimal standard of edible for which it will be considered a violation of Bishul deoritta. Rashi Shabbat 20a D"H Ben Dursai holds that Bishul Deoritta is violated when it reaches half of it's cooking, while the Rambam Shabbat 9:5 holds that once it's reached a third of it's cooking one has violated Bishul Doeritta. Mishna Brurah 253:38 rules like the Rambam. Shemirat Shabbat KeHilchata 1:5 and Shabbos Kitchen (p. 3) agree. 39 Melachos (vol 2, pg 555) and Shabbos Kitchen (p. 3) explain that a third and a half refer to the time that the food would take to cook fully. | * For solid food, 39 Melachos (vol 2 pg 553) writes that the Biblical prohibition is only violated when the food is changed from being inedible to edible.

* Even if a food is already minimally edible, there is a further violation of Bishul when furthering the cooking. S”A 318:4 rules that cooking a food, which is already edible, by any amount which makes it more cooked is a violation of Bishul, unless the food is fully cooked. Biur Halacha D”H Afliu, Shemirat Shabbat KeHilchata 1:5, Shabbos Kitchen (p. 3) agree. | * Even if a food is already minimally edible, there is a further violation of Bishul when furthering the cooking.

* Regarding liquids, S”A 318:14 rules that the Biblical violation of Bishul is violated when the liquid is heated up to Yad Soledet Bo. Shemirat Shabbat KeHilchata 1:5 defines Yad Soledet Bo, in matters in which one has to be strict to avoid any violation, as 113 degrees Fahrenheit. Igrot Moshe 4:74:3, however, rules that one should be strict to consider Yad Soledet Bo as 110 degrees. | * Regarding liquids, S”A 318:14 rules that the Biblical violation of Bishul is violated when the liquid is heated up to Yad Soledet Bo.

* Even if a liquid is Yad Soledet Bo, most poskim hold that there is a Biblical violation of Bishul if one continues to heat it until it reaches its boiling point. Sh"t Igrot Moshe 4:74(3) writes that it's sufficient to assume that once a liquid is 160 degrees heating it further it's permissible to heat it further. However, Otzrot Shabbat in name of Rav Elayshiv, Sh"t Shevet HaLevi 7:42(3), and Minchat Yitzchak 10:28 hold it must reach it's boiling point before being allowed to heat it further. | * Even if a liquid is Yad Soledet Bo, most poskim hold that there is a Biblical violation of Bishul if one continues to heat it until it reaches its boiling point.
