Question: (The Mishnah taught that if he puts the oil in a dish or pot when the contents are still hot, it becomes obligated in Ma'asros) For how long are they considered hot?

Answer (R. Yuda bar Pazi/ R. Simon citing R. Yosi bar Chanina): As long as when one puts his hand in it, it gets scolded.

All agree that in a Kli Sheni (a utensil into which one poured from a Kli Rishon, which is the utensil that had been on the fire), it's (not considered cooking and it is still) permitted (to eat in snack form).

Question: Why is there a difference between a Kli Rishon and a Kli Sheni?

Answer (R. Yosi bei R. Bun): In a Kli Sheni, it has cooled enough that he can put his hand in it; which is not the case with a Kli Rishon.

(R. Yona): In both, he cannot put his hand in it (and the only case where the Torah considers it cooking is a Kli Rishon on the fire), but they made a Rabbinic decree only on a Kli Rishon (off the fire, to prevent a person from putting it in a Kli Rishon on the fire).

(R. Mana): I can support my father (R. Yona's) teaching from a bowl of rice and of barley - as even if it is transferred from place to place, it remains very hot.

Question: Is it permitted to put pour hot water on spices on Shabbos?

Answer (R. Yona): It is prohibited, as pouring from a Kli Rishon is like placing in a Kli Rishon.

Support (Mishnah in Maseches Zevachim): Whether one cooked Kodesh in or poured hot Kodesh (into an earthenware utensil, the utensil must be broken).

Rebuttal (R. Yosi): There, it's because an earthenware vessel absorbs, but here, spices don't cook through pouring.

Reinstatement of support (R. Yosi bei R. Bun - Baraisa): The same applies to when Kodesh was cooked in or poured into a copper utensil (and it requires washing inside and out). Could one say that copper absorbs like earthenware? (Rather, it must be because pouring is like cooking.)

Question: What if a person inserted spices into a stream of water coming from a Kli Rishon (rather than putting the spices in a Kli Sheni and pouring on them)?

(R. Chanina, son of R. Hillel): It's a dispute between R. Yona and R. Yosi.

Question (R. Yitzchak bar Gufta to R. Mana): If a person did this (inserted spices into a stream of hot water) on Shabbos, would he be liable for cooking? And if he cooked meat and milk together in this way, would he be liable for cooking them?

Answer (R. Mana): It's like the teaching of R. Zeira (concerning the obligation of Challah) - It's specifically when a fire is underneath it. Here also, the Torah only considers it cooking when a fire is underneath it.

According to R. Yehuda (of our Mishnah (see earlier Chulin 127(k)), that he may add it to anything (off the fire) aside from that which contains vinegar or brine;) salt is like brine and wine is like vinegar.
