On Rava's opinion about the kohen gadol's griddle-cake offering. The griddle-cake involves flour and oil, but the measurements of each are not clear -- and are therefore subject to interpretation and deriving the details, whether from the verses or logic. Note the recipe that doesn't address taste, but rather learned inferences. Also, a new mishnah! The commitment to the offering of the havitin, even when the kohen gadol whose job it was to bring them has died. Even though one expects the next kohen gadol to have been appointed before the previous one died, but not always... and rather than have the havitin paid for by the treasury, the kohen gadol's heirs had to cover it. Until they went back to having the treasury pay for it, because people weren't abiding by the decree for the heirs to pay.
