Lemon Souffles

Preheat oven to 375 degrees. Butter six 12-ounce souffle dishes, and then dust with granulated sugar. Whisk together yolks, flour, zest, and 2 tablespoons granulated sugar.

Bring milk to a boil in a small saucepan. Slowly pour milk into yolk mixture, whisking constantly to prevent yolks from cooking. Return mixture to pan, and whisk until thick like a pudding, 1 to 2 minutes. Strain through a sieve, and whisk in butter and lemon juice.

Beat whites until foamy. Gradually add remaining 1/4 cup plus 2 tablespoons granulated sugar, and beat until stiff peaks form. Stir a third of the whites into the yolk mixture. Gently fold in the remaining whites using a rubber spatula.

Fill each souffle dish to the top, and smooth. Run your thumb around edges to remove batter from rims.

Bake on a rimmed baking sheet until souffles rise and are golden, about 16 minutes. Dust with confectioners' sugar, and serve immediately, before souffles lose their height.
