Salt
A seasoning that is also a fermentation regulator and, by professional consensus, a modifier of gluten behaviour.
Salt’s most obvious job is flavour, and bread made without it is famously flat — not merely less salty but noticeably lacking in wheat flavour, because salt changes how other flavours are perceived.
Its second job is regulation. Salt restrains yeast activity, slowing fermentation. That sounds like a disadvantage and is usually the opposite: a slower fermentation gives more time for flavour compounds to develop before the dough exhausts its available sugars and its structure degrades.
Its third role — tightening the gluten network and improving dough handling — is stated confidently throughout professional baking literature and is readily observable at the bench. The molecular explanation is offered with more confidence than the underlying evidence supports, so BakeHQ records the effect as professional consensus and is careful about how firmly it states the mechanism.
What changes if it is left out
Fermentation runs faster and is harder to time, dough handles slacker and stickier, and the finished bread tastes markedly flat. In a lean bread the flavour loss alone is decisive.

Measuring salt by volume is unreliable
Salts differ enormously in crystal size and therefore in how much mass fits in a spoon. A teaspoon of fine salt can weigh substantially more than a teaspoon of a flaked salt.
Because bread uses salt at a percentage of flour weight where the workable range is narrow, this is one of the places where a volume measurement genuinely misleads. It is the strongest single argument for weighing in bread baking.

What it does
Flavour contribution
Contributes its own taste and changes the perception of others, which is why unsalted bread tastes flat rather than merely unsalted.
