Мидраш к Вайикра 2:7

1) "And if a meal-offering (baked) on a machavath (griddle) is your offering": We are hereby taught that "machavath" is a vessel. (This has various halachic ramifications.) (It is stated here) "your offering," and, below (Vayikra 2:7), "your offering," for a gezeirah shavah (identity). Just as the offering here requires pouring (of oil) and mixing, so, the offering below. And just as the offering below requires placing oil in the vessel before it (the meal-offering) is processed, so, the offering here.

6) "his full fistful": I might think it should be flowing over; it is, therefore, written (to negate this) (Vayikra 6:8): "in his fistful." If "in this fistful," I might think he can take the fistful with his fingertips (and that they need not reach his palm); it is, therefore, written: "his full fistful." How is this done? He bends three fingers over his palm (and bunches the flour in). And with a machvath or a marchesheth (baked meal-offerings, that do flow over [see Vayikra 2:5 and Vayikra 2:7]), he "erases" (the overflow) with his thumb from above and with his little finger from below.

7) (Vayikra 2:7): "And if a meal-offering of the marchesheth (stewing pan) is your offering": What is the difference between the machavath (griddle) and the marchesheth? The marchesheth has a cover and the machavath does not have a cover. These are the words of R. Yossi Haglili. R. Chanina b. Gamliel says: A marchesheth is deep, and what is baked in it (accordingly) soft; a machavath is flat, and what is baked in it (accordingly) hard. "Of soleth in oil shall it be made": This teaches us that it is first necessary to place oil into the vessel.
