These crispy ghost meringue cookies are the Halloween treat you didn’t know you needed. They are crunchy, light as air, and melt on your tongue like a sweet little secret.
Humidity is your enemy; avoid making meringues on rainy days. Separate eggs carefully to avoid any yolk. Use an oven thermometer to ensure accurate temperature. Let meringues rest in the turned-off oven with the door ajar for 30 minutes to prevent cracking. Store in an airtight container at room temperature for up to 2 weeks; do not refrigerate or freeze.
