Torah Temimah points to Menachos 57b — ban extends to leftover meats and mincha remainders that had an isheh component.
English: From where [do we know] that one who brings up from the meat of a chatas… and from leftovers of minchot [with seor or honey] is under a negative commandment? As it is said, “you shall not turn into smoke from it a fire-offering to Hashem”; anything that had [a part] for the fires is under “you shall not turn into smoke.”
Diyuk on isheh — materials that once contributed an isheh share the ban.
One may not burn seor or honey together with leftovers of offerings that had already sent a portion to the fire. The ban is broader than the azkarah alone; anything that had a share in the ishim falls under the prohibition.
