Cornbread is a generic name for any number of quick breads (a bread leavened by other means, rather than by yeast) containing cornmeal.
As maize (also known as corn) is native to North America, it is not surprising that the various kinds of cornbreads are more prevalent
in the New World. However, in Italy, the corn-based mush known as polenta is sometimes fashioned into a fried form resembling cornbread.
