Ingredients:
- 4 large egg whites, room temperature
- 1 cup granulated sugar
- 1/2 teaspoon cream of tartar
- 1 teaspoon vanilla extract
- Pinch of salt
Instructions:
- Ensure your mixing bowl and beaters are completely clean and dry to prevent any fat from affecting the meringue.
- Add room temperature egg whites to the mixing bowl and whisk on medium speed until frothy (about 2 minutes).
- Sprinkle in cream of tartar and salt, continuing to whisk until soft peaks form (about another 2 minutes).
- Slowly add granulated sugar, 1 tablespoon at a time, while whisking on high speed, until the mixture is glossy and stiff peaks form (about 5-7 minutes).
- Gently fold in vanilla extract with a rubber spatula.
- Carefully spread the meringue over the cooled lemon filling, ensuring it reaches the edges to seal in the filling.
- Preheat the oven to 350°F (175°C) and bake meringue for 10-15 minutes or until golden brown.
- Allow the pie to cool completely before slicing to let the filling set properly.
