1) We will now begin learning the Halachos of the Melacha of "Lisha, Kneading".
In the Mishkan water was added to flour and kneaded into dough for the purpose of producing various breads that were eaten along with the Karbanos as well as to produce Matzos and Chalos for the Mincha and other offerings.
Additionally, various different mixtures of cement, dyes and incense had water added to them and were kneaded to produce items needed for the Avoda (service) in the Mishkan.
Thus, taking smaller elements and adding a liquid or another bonding matter to it and thus forming a combined unit is a prohibition of the Melacha of "Lisha". (In essence, "Lisha" is the exact opposite of "Tochen"; Tochen takes a large item and breaks it down to smaller particles whereas Lisha takes smaller particles and builds them up into a larger item.)
There are various, often complicated, criteria in this Melacha, as we shall B'Ezras Hashem see over the next few weeks.
2) One who combines flour and water or earth and water and kneads it into dough or a cement on Shabbos has transgressed the biblical prohibition of Lisha. (See Rambam Hilchos Shabbos Perek 8 Halacha 16)
It is prohibited to add liquid into a bowl of bread crumbs or Matzah Meal and mix them up together, as doing so is a prohibition of the Melacha of Lisha. (See Biur Halacha Siman 321:14 Dibur Hamaschil V'Afilu)
Likewise, it is prohibited to crumble a cookie or cake and mix them into a soft cheese or into crushed fruit [in the regular manner] in order to feed a baby or ill person as doing so is a prohibition of Lisha. (If done with a Shinui it may be permitted, as we shall discuss in the near future B'Ezras Hashem)

Reader's Question:
Can one cook something that will be put in chicken, and make it in a pot that is used to make fish
?
Answer:
Yes.
Although we don't eat or cook fish and meat together, if no actual fish was in the pot, it is permissible to use what was cooked in that pot with meat. This may even be done L'Chatchila, and as long as the pot is cleaned thoroughly it may be used for both meat and fish on the same day. (See Taz Yoreh Deah Siman 95:3. Most contemporary Poskim rule this way, especially as there are some Poskim including Magen Avraham (quoted in Mishna Berura Siman 173:3) who maintain that today's days there is no Sakana anymore with eating fish and meat together)
That being said, there is indeed a minhag amongst many Jews to retain separate pots for fish and meat, but remember that it is a Chumrah based on a minority ruling(see Tur Yoreh Deah Siman 116:2)
