Step-by-Step Guide to the Best Lemon Meringue Tart

Step 1: Prepare the Tart Crust

1. In a bowl, mix flour, sugar, and salt.

2. Add butter and rub it in until it resembles coarse crumbs.

3. Mix in the egg yolk and add ice water, one tablespoon at a time, until the dough holds together.

4. Form a disc, wrap in plastic, and chill for 30 minutes.

5. Roll out the dough, fit it into a tart pan, and freeze for 20 minutes.

1. In a saucepan, whisk eggs, sugar, cornstarch, and salt until smooth.

2. Gradually add lemon juice, whisking continuously.

3. Cook over medium heat, stirring constantly, until thickened.

4. Once it bubbles, cook for one more minute, then remove from heat.

5. Stir in butter and zest. Pour into the cooled tart crust.

Step 3: Whip the Meringue

1. In a clean mixing bowl, beat egg whites until foamy.

2. Add cream of tartar and salt.

3. Gradually add sugar while beating, until stiff peaks form.
