Gram weights use the King Arthur Baking ingredient weight chart; “—” means the ingredient isn’t on the chart, so measure it by volume or count. Measure flour by spooning it into the cup and leveling, or better, weigh it.
Method
- Heat the oven to 350 °F and line the pan with parchment, leaving overhang.
- Stir the flour, powdered sugar, salt and melted butter into a soft dough and press evenly into the pan. Bake 20 minutes, until lightly golden.
- Whisk the eggs and sugar, then whisk in the flour, lemon juice and zest until smooth.
- Pour over the hot crust and bake 20–25 minutes, until the filling no longer jiggles.
- Cool to room temperature, then chill at least 2 hours. Dust with powdered sugar and cut with a hot knife.
Tips
- Pouring the filling onto a hot crust helps the layers bond.
- About 4 large lemons give 2/3 cup juice.
