- Why did the sponge collapse?
- You probably opened the oven door too soon, and the sudden temperature drop caused the air bubbles to collapse, or you broke the foam too much when mixing.
- Why did it crack when rolling?
- You baked it too long (it dried out), or let it cool flat. The sponge must be shaped (rolled up) while still hot, while the steam makes it pliable.
- Why is it flat and dense?
- The foam wasn't stiff enough, or you didn't sift the flour, and its weight dragged down the foam.
Strawberry Swiss roll

Instructions
Preheat the oven to 180°C (standard setting). Line a baking tray with baking parchment cut to size.
Separate the eggs. Whisk the yolks with half the sugar (60g) and the vanilla sugar until pale.
Start whipping the egg whites with a pinch of salt. When frothy, gradually add the remaining sugar (60g) and whip to stiff, glossy peaks.
Mix a spoonful or two of the foam into the yolk cream to loosen it, then pour this into the rest of the egg white foam. Fold together gently.
Sift the flour onto the mixture in several batches, folding it in carefully after each addition.
Pour the batter onto the tray and smooth it out evenly. Bake for 10-12 minutes until the top is golden brown and springy to the touch.
Prepare a slightly damp, clean tea towel. Turn the baked sponge onto it, peel off the baking parchment, and roll it up with the towel while still hot. Leave to cool like this.
When cooled, unroll, spread generously with strawberry jam, sprinkle with the fresh strawberry pieces, then roll back up (without the towel).
Rest in the fridge for half an hour before serving, then dust with icing sugar and slice into finger-thick swirls.
