Halakhah for Shabbat 204:9

From the laws of the commandment is [that which] they, may their memory be blessed, said (Menachot 21a) that it is a commandment to salt the meat properly - similar to the salting of meat for roasting - such that he salts it from both sides. But it is fit, ex post facto, even if he salted it a tiny bit (Mishneh Torah, Laws of Things Forbidden on the Altar 5:11). And the salt with which we salt the sacrifices is the community's, like the [fire]wood. And an individual does not bring salt or wood for the sacrifices. And all of this is from the aggrandizement of the [Temple]; as 'in a place of wealth, there is no poverty' (Shabbat 102b). And they would put the salt in three places: in the chamber of salt; on top of the ramp; and at the top of the altar. They would salt the limbs in the chamber of salt, and they would salt the handful, the frankincense, the burnt meal-offerings and the burnt offering of the fowl at the top of the altar. And the rest of its details are in the seventh chapter of Zevachim.
