You can stop meringue from weeping by using a mixture of cornstarch and water.
Beat together 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.
To fix a weeping meringue.
Mix 1 tablespoon cornstarch with 1/3 cup water in a small saucepan.
Bring to a simmer, whisking frequently, until thickened. Remove from heat and let cool.
Mix cream of tartar with the extra-fine sugar until well-blended.
To properly beat meringue it takes 5 minutes.
It takes 5 minutes to beat the meringue.
Beating meringue to proper stiff peaks takes 5 minutes and you could use a hand mixer to beat the meringue to stiff peaks.
Hand mixers whether electric or hand crank type hand mixers can be used to make Meringue with although it's best to use a hand whisk.
But a hand mixer can be used to make meringue with as long as you use it properly.
To use your hand held blender to make Meringue move the hand held blender in an up and down motion on high speed which will whip the egg whites to stiff peaks and fluffy perfection.
A blender is not the best way to make stiff egg whites or stiff peaks.
However if done properly the stiff egg whites can be made in a blender but it's best to use a hand whisk to whisk the egg whites to stiff peaks.
A blender can make a mess of the stiff egg whites especially if you do not use the blender on a slow enough speed.
Stiff peaks can be made in a blender if done correctly and you use the correct speed.
You just don't want to turn the blender on too fast or it won't make the stiff peaks properly.
The key to making stiff peaks in a blender is to use the slow setting on the blender.
However it's best to use a hand whisk when beating to stiff peaks so that the stiff peaks turn out properly for your meringue.
A hand blender can be used to make meringue although it's best to use a whisk and whisk the meringue by hand for best results.
The hand mixer may not mix the meringue up properly but if you do use the hand blender or electric mixer to mix the meringue it will turn out just fine.
A countertop blender can also be used to make Meringue with.
If you do use a countertop blender to make Meringue you want to use the slow setting on the blender so it does not blend or mix it too fast.
When making Meringue it's best to blend it with a hand mixer or hand whisk but a countertop blender can work to make Meringue when done right.
You can make stiff peaks with a blender.
To make stiff peaks with a blender you put the blender setting on gentle speed and slow blend it until it's at stiff peaks.
However for best results it's best to beat to stiff peaks by hand mixing it but the electric blender will work to beat to stiff peaks as long as you don't blend it too long.
When making meringue and beating it to stiff beaks it takes around 5 minutes to beat the meringue to stiff peaks.
It can take awhile for the sugar to dissolve and for the meringue to reach stiff peaks.
But it should only take around 5 minutes of beating the meringue before it reaches stiff peaks.
If the sugar in the meringue has not dissolved fully then you still need to beat it some more until the sugar dissolves and so that it doesn't taste gritty.
Once the sugar has dissolved and it doesn't taste gritty anymore then you've beaten it to stiff peaks and it's ready.
But usually 5 minutes is enough to beat to stiff peaks which has been my experience.
