(a) According to Rebbi Yossi, vegetables that were 'Nishlakin' (well-cooked) together with beets of Terumah or of K'lai ha'Kerem - are forbidden (because beets, more than other vegetables) give taste.
(b) He argues with the Tana of the previous Mishnah - inasmuch as the latter forbids all vegetables that have been well cooked together with any Terumah vegetable (not just beets).
(a) Rebbi Shimon discussing a Chulin cabbage that grew in a field of 'Shakya' - (a field that needs to be watered manually) that was cooked together with a cabbage that grew in a field of 'Ba'al' - (that receives sufficient rain-water for its needs).
(b) Rebbi ...
1. ... Shimon rules - that the Chulin cabbage is forbidden (because the former, due to its dryness, absorbs from the latter).
2. ... Yehudah (or Rebbi Akiva) rules that when Isur and Heter are cooked together - they are permitted, with the sole exception of meat (which exudes and absorbs more freely than other species -Tiferes Yisrael]).
(c) The Halachah is - like the Tana Kama, who permits vegetables that have been pickled with Isur (except for Chasis), but not when they have been cooked together.
(a) Rebbi Yochanan ben Nuri rules that when a piece of liver has been cooked together with a piece of ...
1. ... Kasher meat - the latter is Asur (because liver constitutes a hundred per cent blood).
2. ... non-Kasher meat - it does not become forbidden ...
(b) ... because it is busy exuding and does not have time to absorb.
(c) We follow the ruling of Rebbi Yochanan ben Nuri (see Tiferes Yisrael).
The Mishnah rules that ...
1. ... an egg that has been cooked with spices of Isur - is Asur, not only the white, but the yellow, too.
2. ... the water in which Terumah vegetables have been pickled - is forbidden to a Zar.
