Sourdough crackers: another use for starter discard

Useful to know

In King Arthur Baking's Sourdough Crackers recipe, unfed starter discard is mixed with flour, butter and salt. The result is dough for thin crackers, rather than bread intended to gain volume through a long rise. [1]

This distinction explains why the required starter activity differs. Even rolling and baking are central to the result. Using sourdough here is not a basis for attributing live cultures or special health properties to the baked crackers.
