⭐️ Tips For Swiss Meringue
Use fresh eggs. Fresh eggs whip up better and is more stable. Also, do not use egg whites from the carton.
Seperate your egg whites by using the hand method. When separating the egg whites from the yolks, pass the egg whites through your hand rather than passing it back and forth with the shells. The shells are sharp and can pierce the yolks and can fall into your mixture. If you get any yolks into the egg whites, you'll need to start over. The fat from the yolk will hinder it from whipping up.
Be sure to thoroughly clean and wipe your bowl and beaters dry. Your meringue will not whip up properly if your equipment is dirty or wet.
When heating the egg mixture, make sure to use lower heat to prevent steam from creeping up the sides of the bowl. Any moisture that seeps in can prevent your meringue from forming firm peaks. This has happened to me before! 😅
