Permissible ways to heat up food on Shabbat: Difference between revisions

# A pot was on the edge of the blech which isn't above the fire may be moved to the part of the blech which is directly above the fire as long as the area where the pot was originally was as hot as 113 degrees and the food was fully cooked. <Ref> Shemirat Shabbat KeHilchata 1:25 </ref> If one was relying on the lenient opinion which allowed placing food directly onto the part of the blech which isn't directly over the fire one couldn't first place the food on the edge of the blech and then move it to the part of the blech that is directly above the fire.<ref>Shemirat Shabbat KeHilchata 1:26</ref>

# Someone who takes food off the fire on [[Shabbat]] may return it under the following conditions:  

## the food is fully cooked  <ref> S”A 318:4 and Rama 253:2 rule like the Rambam and Tur who hold that unless foods are fully cooked one would violate [[Bishul]] Deoritta, against the Rosh ([[Shabbat]] 3:10-11) and Rashba ([[Shabbat]] 18b) who hold that once food is cooked KeMachal Ben Dursai it’s permissible to cook it even until it’s fully cooked food. Therefore, one may not return to the fire any food that’s not fully cooked otherwise there’s a potential Deoritta violation of [[bishul]]. Accordingly, Biur Halacha 318:4 D”H Shayach writes that even if one is in doubt whether the food is fully cooked or not one may not return the food to the fire. So brings Shemirat Shabbat KeHilchata 1:18 note 55. </ref>
