 * 1 cup plus 1 tablespoon granulated sugar 
 * 1/4 cup honey 
 * 1 teaspoon vanilla extract 
 * 1 teaspoon lemon extract 
 * 1/4 teaspoon salt 
 * 7 large eggs, separated

 * In a large bowl, whisk 1 cup sugar, honey, vanilla, lemon extract, and salt into egg yolks. Place bowl in a large pan of hot water. With an electric mixer, beat about 5 minutes on medium-high speed until pale yellow and doubled in volume. Gently fold in sifted flour
 * In a large bowl, beat egg whites in electric mixer on a low speed 1 minute, increasing speed to medium-high. When foamy, sprinkle in 1 tablespoon sugar and cream of tartar. Beat until stiff but not dry. With a spatula, fold the egg whites in thirds. Pour batter into pan. Tap gently on the counter to remove air bubbles

 * Cool 20 minutes. Run a small knife between edge of cake and pan. Remove from pan carefully. Pull off parchment and cool completey. Serve or store airtight.
