cellio | daf bit: Menachot 18

A note in the Soncino edition of the talmud explains the procedure for a meal-offering: first some oil was poured in a vessel and then some fine flour was put in; then more oil was poured in and it was mingled with the flour. Then it was baked into cakes and broken in pieces. The remainder of the oil was poured on it, and the handful was taken from there. That's the baseline. The mishna now talks about deviations: if he didn't pour in the oil (at the end), or he didn't mingle it, or he didn't break the whole cake into pieces, or he didn't salt it, or he didn't wave it or bring it to the horn of the altar, or broke it into pieces that are too large or too small, or he didn't annoint it with oil when he needed to -- for any of these deviations, it is nonetheless a valid offering.
