Preheat your oven to 200°F (90°C).
Separate egg whites from yolks, ensuring no yolk gets into the whites.
In a large mixing bowl, add the egg whites and a pinch of salt.
Using an electric mixer, beat the egg whites on medium speed until foamy.
Add cream of tartar and continue beating until soft peaks form.
Gradually add granulated sugar, one tablespoon at a time, while mixing on high speed.
Once all sugar is added, beat until stiff peaks form and the mixture is glossy.
Mix in vanilla extract gently with a spatula.
Pipe or spoon the meringue onto a lined baking sheet.
Bake for 1 hour, then turn off the oven and let meringues cool inside.
