So, what exactly happens when cookies go bad? Well, it's pretty simple: they become stale and dry, losing that soft, chewy texture we all know and love. It's kind of like when you leave a piece of bread out on the counter for too long and it becomes all crusty and gross.
But why does this happen? It all comes down to the moisture levels in the cookie. When cookies are fresh, they're full of moisture, which keeps them soft and delicious. However, over time, that moisture starts to evaporate, leaving the cookie dry and stale. It's like when you take a soggy sponge and leave it out to dry - it's just not the same anymore.
And then there's the issue of bacteria and mold. If cookies are exposed to too much moisture or heat, they can become a breeding ground for these microscopic critters. It's not exactly what you want to think about when you're snacking on a cookie, but it's a reality we have to face.
