Cornbread
A chemically leavened batter bread with almost no gluten to speak of — which makes nearly every intuition from yeasted baking the wrong one.
Also called corn bread (US), skillet cornbread (US), johnnycake (US), corn pone (US)
Cornbread is a quick bread: a pourable batter of cornmeal, usually with some wheat flour, raised by a chemical leavener and baked immediately. Calling it bread is a naming convention rather than a structural claim — it has no fermentation, no developed gluten network, and nothing in common with a yeasted loaf except the word.
ITS STRUCTURE COMES FROM STARCH AND EGG rather than from gluten. Maize has no gluten-forming proteins, so whatever network exists comes from the wheat flour in the mix, and many traditional formulas contain very little or none. What holds the crumb together is gelatinised starch setting as it cools, supported by coagulated egg protein.
That explains the two things people find surprising about it. It is CRUMBLY by nature, and increasing the wheat flour is the direct lever on that; and it goes stale quickly, because a starch-set crumb with no gluten network and comparatively little fat has less holding it together as retrogradation proceeds.
The cornmeal grind matters more than the recipe usually says. Coarse meal hydrates slowly and gives a distinctly gritty crumb; fine meal gives a smoother, cakier one. Neither is wrong, and a recipe written for one and made with the other produces a different bread.
The long-running argument about sugar in cornbread is regional rather than technical. Sugar changes the browning, the tenderness and the keeping as it does anywhere, and BakeHQ takes no position on which version is correct.

How it keeps
Stales quickly by the standards of a yeasted loaf. A crumb set by gelatinised starch with little or no gluten network and comparatively little fat has less holding it together as retrogradation proceeds, and it is usually best on the day.
Follows from the structural account above and from the retrogradation record. No shelf-life study has been consulted and no keeping time is stated.

Where it comes from
Professional consensus
Agreed by professional bakers and baking-science texts, with an accepted mechanism, though not isolated by controlled experiment.
Maize baking is indigenous to the Americas and long predates the European-style quick bread now called cornbread. The chemically leavened form is a nineteenth-century development on much older maize cookery.

Why cornbread is crumbly, and when that is a fault
Crumbliness is the default state of a bread with little or no gluten, and a great deal of cornbread is crumbly on purpose.
It becomes a fault when it will not hold together enough to be served. The levers, in order of effect: more wheat flour, which adds the only gluten in the formula; more egg, which adds protein that sets; more fat, which is counterintuitive but binds by shortening the structure into something that fractures cleanly rather than shedding; and letting it cool completely, because a starch-set crumb is still setting while warm.
What does NOT help is mixing it more. There is not enough gluten present for development to build strength, and over-mixing a chemically leavened batter costs gas and gives tunnels.

Part of
Filed as bread because that is what it is called and where readers look. Structurally it is a quick bread with almost no gluten, and the record says so rather than implying a yeasted loaf.
What this product needs done
Structure building
Gelatinised starch setting as it cools is the primary structure. Maize contributes no gluten-forming protein at all.
Structure building
Egg protein supports what the starch sets, which is why removing the egg makes it markedly more fragile.
Aeration
A chemical leavener, acting once and immediately. Nothing is fermented and nothing is whisked.
Hydration
A pourable batter, so it carries a great deal more liquid than a dough — and coarse cornmeal takes that liquid up slowly.
Techniques this product depends on
A chemically leavened batter is mixed until just combined and no further. There is not enough gluten present for development to build strength, and over-mixing costs gas and gives tunnels.
Characteristic ingredients
Acting once and immediately, which is why the batter goes into the oven as soon as it is mixed.
Things that go wrong
THE PRODUCT-LEVEL EDGE. Cornbread is filed under bread and goes dry the way a quick bread does, so the family rule alone would refuse it. The graph says so explicitly and the search bridge prefers the product over the family for exactly this case. SPRINT 21 NARROWED THE OTHER SIDE OF THIS PAIR. Cornbread also carried `bread-crumbly`, and once `crumble` and `fall apart` became symptom vocabulary the two models became reachable by the same words for the same product — BAKE-V024 refused it, correctly. The bread crumbliness model is about a gluten network weaker than the method assumed, and cornbread has no gluten network to weaken. This edge is the right one and the other was removed.
