LEMONY ANGEL FOOD CAKE

Steps:

• Make the cake: Preheat oven to 325 degrees, with rack in lower third of oven. Sift flour and 1/2 cup sugar into a bowl.
• Whisk whites with a mixer on medium speed until frothy, about 1 minute. Add lemon zest and juice, cream of tartar, vanilla, and salt; continue whisking until soft peaks form, about 2 1/2 minutes. With mixer running, gradually add remaining cup sugar.
• Increase speed to medium-high; continue whisking until firm, not stiff, peaks form, about 7 minutes. Sprinkle whites with 1/3 of the flour-sugar mixture. Using a rubber spatula, gently fold to combine. Sprinkle remaining flour-sugar mixture over whites in 2 additions; gently fold to combine.
• Transfer batter to a 10-inch angel food cake pan with legs. Gently run a knife through the center of the batter to remove any air bubbles. Bake until a tester inserted into center comes out clean, 45 to 50 minutes.
• Remove pan from oven, and invert onto its cooling legs (if your tube pan doesn't have legs, invert it over the neck of a wine, or similarly shaped, bottle to cool); let cool, 1 1/2 to 2 hours. Run a knife around the inner and outer edges of cake to remove. Invert onto a serving platter. (Use a knife to separate cake from bottom of pan.) Let cool on a wire rack. Unfrosted cake can be stored in an airtight container for up to 2 days.
• Make the lemon cream: Prepare an ice-water bath. Whisk lemon juice, sugar, flour, and salt in a small saucepan over medium-high heat. Bring to a boil; whisk constantly for 1 minute, until it thickens. Transfer to a heatproof bowl set in ice-water bath to cool completely, stirring occasionally. Meanwhile, whisk cream and lemon zest with a mixer on medium speed until medium peaks form, about 3 minutes. Gently fold whipped cream into juice mixture in thirds. Refrigerate lemon cream, up to overnight.
• Make the candied lemon-peel flowers: Combine sugar and water in a large saucepan over medium-high heat, stirring until sugar dissolves. Bring to a simmer. Meanwhile, using a vegetable peeler, peel 3 lemons to create 6 long strips (at least 5 inches long and about 1/2 inch wide). Remove pith from strips using a paring knife. Cut tops and bottoms off remaining 3 lemons; cut each in half lengthwise. Remove flesh. Cut out 6 flowers from the peels using a 2-inch flower-shaped cookie cutter and remove pith; cut indentations into petals for definition. Punch a hole in the center of each flower using a 1/4-inch plain round piping tip.
• Add lemon-peel strips and flowers to the syrup. Gently simmer until translucent and tender, about 35 minutes. Remove peels from syrup using a slotted spoon, and transfer to a wire rack set over a parchment. Let dry slightly, about 30 minutes.
• Trim strips to 5-inch lengths, and roll each to form centers of flowers; fit into flower holes and let stand on wire rack until slightly dry but still sticky, about 30 minutes.
• Frost cake with lemon cream. Garnish with candied flowers. Serve.
