Method

Sponge

  1. Preheat the oven to 350°F (170°C) convection (fan). Line the bottom of a springform pan with parchment paper.

  2. Beat the eggs, salt, sugar & vanilla sugar for about 10 minutes. If you like, you can separate the eggs instead: beat the egg whites with these ingredients until stiff, then let the yolks run in briefly with the mixer going.

  3. Mix the flour & cornstarch, sift them over the egg mixture and fold them in with love, drizzling in the melted butter as you go.

  4. Pour the batter into the pan and bake on the middle rack of the oven.

  5. After baking, let the sponge cool in the pan.

  6. Once the sponge has cooled, release it from the pan and cut it in half horizontally.

  7. Set the springform ring back around the bottom layer. If you have one, now place an acetate cake collar around the sponge layer as well.

  8. Slice the strawberries and arrange them in the springform pan.

Filling

  1. Wash the strawberries, remove the green tops and dice them.

  2. Peel the rhubarb, cut it into thumb-sized pieces and cook it with the water, sugar & vanilla sugar for a few minutes.

  3. Add the agar-based gelling powder and bring everything back to a boil for two minutes, stirring, then let it cool until the mixture is lukewarm.

  4. Whip the cream until stiff and fold it into the rhubarb mixture together with the strawberries.

  5. Spread about ¾ of the filling into the pan, place the top sponge layer on it and spread the rest of the cream over it, then chill for at least three hours.

Finishing

  1. Whip the cream, sprinkling in the vanilla sugar and whipped cream stabilizer as you go, then transfer it to a piping bag and pipe rosettes on top.

  2. Decorate the cake with strawberries, rhubarb and pistachios.
