Ma'aseh Shabbos

(4) 4. If a dish has been thoroughly cooked, the prohibition of cooking still applies if it has cooled down. RMA - There are those who say that this only applies if the dish continues to improve in quality (Rabeinu Yerucham); And if the dish has not been fully cooked - even if it has been partially cooked - the prohibition of cooking applies to it even when it is still hot. And this which we have said that the laws of cooking apply to a cooked dish applies only to dishes with liquid. However, a dish which is cooked and is dry may be placed in hot water on shabbat. If it is a dry food which which was not cooked prior to shabbat, one may not place it into hot water, but one may pour hot water on to it, excepting old herring and Spanish tuna which only need a small amount of cooking and pouring will cook them. RMA - This is the case for all hard things which aren't edible at all without soaking - one may not soak them as this completes their cooking process.

(5) 5. There are those who hold that a thing which as been previously roasted or baked is prohibited by the laws of bishul to be cooked again in water - and it is forbidden to put bread, even in secondary vessel which is hot enough to cause the hand to recoil. There are those who permit this. RMA - In a secondary vessel. There are those are lenient even in a primary vessel (which was at one point on the flame) and the custom is to be strict in the first instance not to put bread into a secondary vessel the entire time that it is hot enough to cause a hand to recoil from it.

(9) In the case of a primary vessel (meaning a vessel which is used on the fire) even after it has been removed from the fire it can cook items placed in it, as long as the pot is less than Yad Soledet Bo. Therefore, it is forbidden to place in it spices (category of tavlin), however, Salt may be placed in it… GLOSS: …there are those who prohibit placing salt in a secondary vessel as long as the temperature is above Yad Soledet Bo, a blessing should come to those who are stringent…

(11) Regarding a tub for washing [a human] which is full of hot water (even though it is as a secondary vessel) [Tosafot, Rosh, Tur]: it is forbidden to pour cold water into it as it will heat up the water quite a bit. However, one may put hot water from one tub into another tub which contains cold water.

(12) Regarding an urn which has been emptied of water, one is permitted to put [much] water inside of it in order to make the water temperate. It is also permitted to pour hot water into cold water, or cold water into hot water - this is on the condition that it is not into a primary vessel, as that will heat the water very much. RMA - And if the water is so plentiful that it is impossible that it will cook, rather it will only become temperate, this is permissible even into a primary vessel provided that it is no longer on the flame.

(13) It is permissible to place an ewer of water or any other liquid into a secondary vessel which contains hot water. It is forbidden to do this in a primary vessel.

(14) It is permissible to place an ewer of water or other liquid near a fire in order to make the liquid temperate, provided that it is far enough away that it cannot reach the point where it becomes hot enough for the hand to recoil (hot enough to burn), that is a place which is hot enough that the abdomen of a baby will be burned. It is forbidden, however, to bring it close enough to the fire where it is in a place that it can heat up to the level that the hand will recoil; this applies even to leave it there for a few moments in order to warm the water because the ability to cook the water exists. RMA - this is the law regarding fruits and all food which can be eaten raw.

(15) Food which is cooked thoroughly and is dry without any liquid, one may place next to the flame, even in a place where it will become hot enough for the hand to recoil. RMA - even if it has cooled down already. But if it is still hot, even a food with liquid may be placed there. And there are those who are lenient and say that as long as one doesn't place it directly on the fire or stove, rather near it, even if it is completely cold, it is permitted. And the custom is to be lenient on this as long as it hasn't cooled down completely.

(16) It is permissible to put an empanada near the fire in a place where the hand will recoil, even though the congealed fat contained inside of it will melt. RMA - All the more so with a pot of food which has congealed sauce, when the melted fat is not recognisable, it is permissible. And there are those who are strict. The custom is to be strict, but in a case where there is need, one may trust the first opinion.

(17) It is forbidden to put cold liquid on top of an urn, even just to warm it up, as long as the urn is hot enough to cook if the food is left long enough - this is that the urn is hot enough to cause a hand to recoil. The laws pertaining to an urn are the same as those pertaining to a hot stove. If the urn is not so hot, it is permissible.
