Allow egg whites to sit at room temperature for 30 minutes before whipping—they'll reach stiff peaks faster and create a more stable, voluminous meringue structure.

Add a pinch of cream of tartar or lemon juice to your egg whites before beating to stabilize the foam and prevent weeping or collapsing during baking.

Bake meringues at 200°F or lower for 1-1.5 hours to dry them out gently rather than brown them—this preserves the marshmallow interior while achieving a crispy shell.

Add sugar gradually while beating and test by rubbing a small amount between your fingers—it should feel completely smooth with no grittiness for silky-smooth cookies.

Turn off the oven and crack the door open slightly, leaving meringues inside for 30 minutes to cool gradually and prevent cracking from temperature shock.
