Preparation
Step 1
Put oven rack in middle position and preheat oven to 400°F. Butter a 9 1/2-inch deep-dish glass pie plate.
Step 2
Bring milk, 1/4 cup granulated sugar, cornstarch, and zest to a boil over moderate heat in a 2-quart heavy saucepan, whisking constantly. Boil, whisking, 1 minute. Remove from heat and whisk in butter, juice, and liqueur until butter is melted, then whisk in yolks until blended.
Step 3
Beat whites with salt in a large bowl using an electric mixer at medium speed until they just hold soft peaks. Add remaining 3 tablespoons granulated sugar a little at a time, beating, then beat until whites just hold stiff peaks.
Step 4
Fold one fourth of whites into yolk mixture to lighten, then fold in remaining whites gently but thoroughly. Spread in pie plate with a rubber spatula and bake until puffed and golden, 16 to 18 minutes. Dust with confectioners sugar and serve immediately.
