How to tell if barley flour has gone bad

  • A sour, rancid smell the moment the bag opens
  • A bitter aftertaste in the finished crumb
  • Silky webbing across the top of the flour
  • Lumps set solid against the side of the bag

When in doubt, throw it out.

Let frozen flour come back to room temperature before you open the bag — opened cold, it pulls condensation straight out of the air.
