THE UPSHOT: As long as you pack meringues in an airtight container immediately after cooling them, any humidity in the air doesn't matter. WEATHERPROOF IT: To maintain crispness, pack meringues in an airtight container as soon as they're cool.

How to store uncooked meringue mixture. To store your uncooked meringue, move it into an airtight container, cover it, and refrigerate it. Use your mixture within the day, or you can transfer it into the freezer.

Once your meringues are cool, place them in an airtight container, with parchment paper in between the layers to prevent them from crushing each other in the container. Store them at room temperature for up to 3 weeks, or keep them in the freezer for up to 1 month.
Beat a mixture of thickened cornstarch and water into the egg whites to bind and stabilize the liquid in the meringue (and keep it from seeping out). Cook the filling for the full 2 minutes on the stove top so the cornstarch thickens completely and doesn't start breaking down and "leaking" during chilling.
It's best to make meringues on a dry day. On humid or rainy days, they can absorb moisture and become limp or sticky.
Can you beat meringue too long?
As my meringue guru Gary Mehigan advises: “If you over whip the egg whites you cannot fix it. You've just got to start over.” So start whisking on a medium speed to get soft peaks and then speed up the mixer when the sugar is added. A soft peak is one that peaks but then the tip of that peak softly collapses on itself.

How to keep meringue cookies white. I usually bake the cookies at 200F/90C and they turn out white. However, if your cookies have a slight tint after baking, decrease the temperature to 175F/80C next time – no lower than that – and increase the baking time.
Older egg whites tend to not hold the air bubbles as well as fresher whites, which can cause them to collapse. A more common cause of collapse, though, is that when the whites are beaten too quickly (on too high a speed) they form big unstable air bubbles, which will later collapse.
Some recipes call for a small amount of cream of tartar or cornstarch, which helps stabilize the meringue and prevent it from deflating.
Weeping is caused by an unstable meringue, one that is undercooked or that it simply has too much moisture in it. Many pies are topped with a meringue made by beating sugar and egg whites together, spreading it onto a hot pie and baking it for a few minutes in the oven to brown it.

Why do my meringues go soft?
Not enough sugar.
The less sugar, the less effective the evaporation process will be during baking, which will leave excess moisture behind and result in a soft meringue. The higher the sugar content, the more effective the evaporation of moisture, and the crisper the baked meringue will be.
Bake in preheated 275°F (140°C) oven until firm, about 30 to 35 minutes. Cool completely on wire racks.
Make sure you're spreading your meringue over a hot — not cooled — pie filling. Otherwise, your meringue will bake on top, but the cooled pie filling won't get hot enough to cook the meringue on its bottom in the short 15 to 20 minutes needed to bake a meringue.
Cream of tartar stabilizes the tiny bubbles in the egg whites, by precluding the egg proteins from sticking together. It thus speeds up the egg white whipping process and contributes to a stable, billowy, glossy meringue, perfect for cookies, topping pies, and folding into cake.
Normally, when left at room temperature and stored properly in an airtight container, meringues can stay fresh for 2 weeks. If the dessert was put in the freezer, it can even last for months.
