Line a 12 1/2-by 17 1/2- inch rimmed baking sheet with parchment paper; coat with cooking spray. Dust with flour, and tap out excess.
Combine dry ingredients Whisk together flour and salt in a bowl.
Combine eggs and sugar Bring about 2 inches of water to a simmer in a medium saucepan. In the heatproof bowl of an electric mixer set over (not in) simmering water, whisking eggs, yolks, and granulated, sugar until sugar has dissolved and the mixture is warm to the touch.
Attach bowl to mixer fitted with the whisk attachment; beat on medium-high speed for 2 minutes. Raise speed to high; beat until mixture is pale and thick, about 4 minutes more.
Add dry ingredients Sift flour mixture over egg mixture using a large rubber spatula, carefully fold.
When almost incorporated, pour melted butter down side of bowl; gently fold to combine.
Bake Using an offset spatula, spread batter evenly into prepared sheet.
Bake cake until golden brown and springy to the touch, 6 to 7 minutes. Meanwhile, dust a clean kitchen towel with confectioner's sugar.
Run a knife around sides of a cake. Invert onto prepared towel, and remove parchment.
Roll into a log and cool While the sheet cake is still warm, gently roll, starting from one short side, into a log, incorporating the kitchen towel.
Let the cake cool completely, rolled. ( this will give the cake shape memory", so it will be easier to roll again with filling.)
Fill cake and reroll Unroll cake. Spread with jam, leaving 1/2 inch border on all sides.
In a mixing bowl with a whisk or electric mixer, whip cream until soft peaks form;
Spread evenly over jam with an offset spatula. Roll cake to enclose filling (without towel), starting at a short end.
Wrap the towel around a rolled cake, securing the clips to help retain the shape.
Chill a serve Refrigerate cake 30 minutes ( or up to 3 hours). Dust with confectioners sugar, cut into slices with a serrated knife and serve.
