Regarding all of these, the Kohanim may vary the [manner of] their consumption, to eat them roasted, overcooked, or cooked, and to add to them non-sacred spices and spices of terumah; [these are] the words of R’ Shimon. R’ Meir says: One may not add spices of terumah to them, so that he not expose the terumah to disqualification.

Said R’ Shimon: If you see oil being distributed in the Courtyard, you need not inquire what it is — it is either the remainder of the wafer minchah-offerings of Yisraelim or of the log of oil of a metzora; if you see oil being poured upon the fires you need not inquire what it is — it is either the remainder of the wafer minchah-offerings of Kohanim, or of the minchah-offering of the Anointed Kohen — for oil cannot be donated. R’ Tarfon says: One can donate oil.
