1. Method
2. Make the cake
3. 1. Into a large bowl, sift together the cake flour, sugar, baking powder and salt twice.
4. 2. In another bowl, beat the egg yolks, water, vegetable oil, lemon zest and vanilla on high speed until smooth. Stir into the flour mixture until smooth.
5. 3. In a third bowl, beat the egg whites and cream of tartar on medium speed until soft peaks form. Gradually add the sugar, beating on high speed until peaks are stiff but not dry.
6. 4. Use a rubber spatula and fold one-quarter of the egg whites into the egg yolk mixture, then fold in the remaining whites. Scrape the batter into an ungreased 10-inch tube pan with a removable bottom and spread evenly. Bake in a preheated 325u0b0F (160u0b0C) oven until the top springs back when lightly pressed and a toothpick inserted into the center comes out clean, 55 to 65 minutes.
7. 5. Let cool upside down for at least 1 1/2 hours, setting the tube over a bottleneck or resting the pan on four glasses.
8. 6. To unmold, slide a thin knife around the cake to detach it from the pan, pressing the knife against the pan to avoid tearing the cake. Using the same procedure, detach the cake from the center tube. Pull the tube upward to remove the cake from the pan side. Slide the knife under the cake to detach it from the bottom. Invert and allow the cake to drop onto your hand, a rack, or a serving platter. Invert again, right side up, on a rack to cool complete before icing.
9. Make the icing
10. 1. Melt the butter in the top of a double boiler over low heat. Remove and stir in the powdered sugar, lemon juice, zest and salt.
11. 2. Return to heat and cook over barely simmering water for 5 minutes, stirring occasionally. Remove and add the vanilla.
12. 3. Beat until cool (briefly for a pourable glaze or several minutes for a spreadable icing). You can place the pan in a larger pan of ice water to quicken the process.
13. 4. Drizzle or spread over the cake. Let set before serving
