Ingredients for 79 servings

• 5 cups unsalted butter, melted
• 2 1/2 cups granulated sugar
• 2 1/2 teaspoons kosher salt
• 9 7/8 cups all-purpose flour
• 30 large eggs
• 9 7/8 cups granulated sugar
• 5 tablespoons lemon zest
• 5 cups fresh lemon juice
• 1 2/3 cups all-purpose flour

1. Step 1 of 5

   Heat the oven to 350°F. Line the pan with parchment, leaving some overhang to lift the bars out.

2. Step 2 of 5

   Stir the melted butter, 1/2 cup sugar and salt, then mix in 2 cups flour. Press evenly into the pan and bake 18 to 20 minutes, until lightly golden.

3. Step 3 of 5

   While the crust bakes, whisk the eggs, 2 cups sugar and zest until smooth. Whisk in the lemon juice, then the 1/3 cup flour.

4. Step 4 of 5

   Lower the oven to 325°F. Pour the filling over the hot crust and bake 22 to 25 minutes, until the center barely jiggles.

5. Step 5 of 5

   Cool to room temperature, then chill at least 2 hours. Lift out, dust with powdered sugar and cut with a hot, dry knife.
