2 tablespoons (30 mL) cornstarch
1 tablespoon (15 mL) finely grated, lemon rind, firmly packed (most of one lemon)

5 large eggs, at room temperature
1 large egg yolk, at room temperature

2 tablespoons (30 mL) unsalted butter, melted and cooled

Extra confectioner’s sugar for dusting

Method:

1. Line a 9 x 12 baking pan (preferably one with straight sides) with parchment paper. For easy removal after baking, make a ‘sling’ with two sheets of parchment paper.
2. Make the Crust: In the bowl of a food processor, place flour, confectioner’s sugar, cornstarch, lemon rind, and salt. Pulse until well mixed.
3. Gradually add butter chunks, and pulse until mixture resembles coarse crumbs.
4. Dump crust mixture into pan and press it evenly all over the bottom.
5. Place pan in the freezer; preheat oven to 350⁰F (180⁰C).
6. When the oven is hot, pre-bake the crust for 15 or 20 minutes, or until it is a very light golden brown.
7. Make the Lemon filling:  Put the lemon juice and lemon rind in food processor and process for a few seconds.
8. Add sugar, flour, baking powder, and salt. Process for a few seconds, or until well mixed.
9. Add eggs and egg yolk; process again until very well mixed. Stir in melted butter.
10. Gently pour over baked crust.   Reduce oven heat to 325^oF (165^oC) and bake an additional 30-35 minutes, or until set.
11. Let cool completely in pan.   Remove to cutting board and cut into bars.
12. When cool, dust with confectioner’s sugar.
