Your senses are your best tools. A fresh meringue makes a crisp, clean snap when you bite it. If it feels soft, sticky, or rubbery, it has absorbed too much moisture and is past its prime.
Smell is another giveaway. Meringues are mostly sugar and egg whites, so they don’t “go bad” in the same way a dairy product does. But any off, sour, or yeasty smell means it’s time to toss them—sugar can ferment if exposed to enough moisture and time.
One more hint: If you see tiny cracks or weeping (little beads of syrup on the surface), that’s a sign of “weeping” meringue. It happens when the sugar hasn’t fully dissolved or humidity got to them. These cookies are still technically safe, but they won’t deliver that signature crunch.
Reviving a Slightly Soft Meringue
Don’t throw them out just yet! If your meringues have gone a bit soft but aren’t spoiled, you can try to revive them. Place them on a baking sheet in a 200°F (93°C) oven for about 10–15 minutes, then let them cool completely in the oven.
This low-and-slow re-bake forces out the excess moisture and restores their crunch. It’s like giving your cookies a little spa day. But be warned: this trick only works once, and only for cookies that haven’t gotten wet or sticky.
Of course, the best plan is to eat them within the first week. That’s when the texture is most heavenly—that perfect combination of brittle exterior and melt-in-your-mouth interior.
