Menahot 11: A Fistful of Grain, with Frankincense on the Side

More on the kohen's fistful from the grain - ensuring no barrier to the grain itself. Plus, the physical description of how to take the grain in one's hand, with the understanding of a basic action - namely, what it means to take a handful. But what about if one used fingertips? Are all fingers supposed to be involved? The Torah has phrasing from which some details may be gleaned. Also, the frankincense! Which itself is (usually) essential to the menahot. Plus, a dispute about what happens for an offering of frankincense on its own, as compared together with the grain-offering (or the lehem hapanim).
