- Why did the sponge collapse?
- You likely opened the oven too early, shocking the air bubbles with cold air, or you deflated the foam while mixing.
- Why did it crack when rolling?
- You baked it too long (dried it out) or let it cool flat. You must roll it while hot so the steam keeps it pliable.
- Why is it flat and dense?
- The egg whites weren't stiff enough, or you didn't sift the flour, weighing down the foam.

Instructions
Preheat oven to 350°F (180°C). Line a jelly roll pan (10x15 inch) with parchment paper.
Separate the eggs. Beat yolks with half the sugar (1/4 cup) and vanilla until pale and thickened.
Beat egg whites with salt. When foamy, gradually add the remaining sugar (1/4 cup) and whip to stiff, glossy peaks.
Fold a dollop of whites into the yolks to lighten them, then pour that mixture into the remaining whites. Fold gently.
Sift flour over the batter in batches, folding gently after each addition.
Spread evenly in the pan. Bake 10-12 minutes until the top is golden and springs back when touched.
Prepare a clean, slightly damp kitchen towel dusted with powdered sugar. Flip the hot cake onto it, peel off parchment, and roll it up with the towel. Let cool completely.
Unroll, spread with jam, sprinkle with strawberries, and re-roll (without the towel).
Chill for 30 minutes, dust with powdered sugar, and slice.
