. However, during several instances of famine (especially in European countries throughout history), people have been known to eat the corncobs, especially the foamy middle part. The whole cob or just the middle used to be ground and mixed with whatever type of flour was available (usually wheat or corn flour). It served as a sort of peculiar "filler", to extend the quantity of the original flour and as such, it was used even in production of bread. The cob is not toxic to humans and can be digested, but the outside is rough and practically inedible in its original form. The foamy part has a peculiar texture when mature and is completely bland, which most people would find unappealing, due to the consistency similar to foam plastic. Corncobs are a particularly good source of heat when burned, so they were traditionally used for roasting meat on the spit, barbecuing and heating the bread ovens, through the centuries. In the olden days, it was especially appreciated for its long and steady burning embers, also used for the ember irons. Pannocchia sgranata

When harvesting corn, the corncob may be collected as part of the ear (necessary for corn on the cob), or instead may be left as part of the corn stover in the field.
