Strawberry Lemon Jelly Roll
 
Makes 10 servings
Ingredients
  • ¾ cup (94 grams) cake flour, sifted
  • ¾ teaspoon (3.75 grams) baking powder
  • ¼ teaspoon kosher salt
  • 4 large eggs (200 grams), room temperature and separated
  • ⅔ cup (133 grams) granulated sugar, divided
  • 2 lemons (198 grams), zested
  • 1 tablespoon (14 grams) fresh lemon juice
  • 1 cup (120 grams) confectioners’ sugar, for dusting
  • Strawberry Mascarpone Buttercream (recipe follows)
  • Garnish: confectioners’ sugar, fresh strawberries
Instructions
  1. Preheat oven to 350°F (180°C). Spray a 15x10-inch jelly roll pan with cooking spray. Line pan with parchment paper, and spray pan again.
  2. In a small bowl, sift together flour, baking powder, and salt. Set aside.
  3. In the bowl of a stand mixer fitted with the whisk attachment, beat egg yolks and ⅓ cup (66.5 grams) granulated sugar at high speed until thick, pale, and ribbonlike. Add lemon zest and juice, beating until combined. Transfer batter to a large bowl; set aside.
  4. Clean bowl of stand mixer. Using the whisk attachment, beat egg whites at medium speed until foamy. Gradually add remaining ⅓ cup (66.5 grams) granulated sugar; increase mixer speed to high, and beat until soft-medium peaks form. Fold egg whites into yolk mixture in 2 additions until no streaks remain. Fold in flour mixture. Quickly spread batter into prepared pan. (Do not overwork batter or it will deflate.)
  5. Bake until a wooden pick inserted in center comes out clean, about 8 minutes.
  6. Meanwhile, dust confectioners’ sugar into a 15x10-inch rectangle on a clean dish towel. Immediately loosen cake from sides of pan, and turn out onto prepared towel. Gently peel off parchment paper. Starting at one short side, roll up cake and towel together, and place seam side down on a wire rack. Let cool completely.
  7. Gently unroll cake, and spread with Strawberry Mascarpone Buttercream, leaving a ½-inch border. Reroll cake without towel, and refrigerate for 30 minutes before serving. Garnish with confectioners’ sugar and strawberries, if desired.
