Eli5: Why does a slice of bread keep cookies fresh?


We always out a slice of bread in with fresh baked cookies. It gets hard while the cookies stay fresh. My son asked why and honestly, I havent thr slightest. Just know it works.
Also, if the bread touches the cookie it will make it soft where it touches.

And the cookie doesn’t absorb any wierd bread flavour!? This sounds just crazy enough to work and I will now try your method, Sire or Madam

The bread is relatively high moisture and as it dries out, the cookies absorb the moisture which makes them stay moist and fresh. If you put the cookies in a bag with uncooked rice for instance, the opposite would happen and the cookies would dry out and become hard.
